Hello everyone, and hope you've all had a good day so far. I am currently having a break after putting most of my bookcase together. Here are some fossil plants found in the Triassic layers of the Sydney Basin I would like identified if possible. As before, I would like the most specific identification possible, but don't mind genus or clade names if they'd be more accurate. I know the general location for these, so don't worry about that. If you need more photographs for a proper identification, I can take more in a couple of hours or tomorrow. Specimen 1: Shale plant fossil This fossil was found by a friend in the shale rock layer in the Northern Beaches region. This makes it Triassic in age. I read this document (https://www.researchgate.net/profile/Gregory-Retallack/publication/241677571_Geological_excursion_guide_to_the_sea_cliffs_north_of_Sydney/links/55d2119008ae0b8f3ef776a9/Geological-excursion-guide-to-the-sea-cliffs-north-of-Sydney.pdf) and after comparing the plant to various images on the document, I came to the conclusion that the plant was a specimen of the seed fern Dicroidium. Is this an accurate identification? Specimen 2: Plant Assortment This assortment of various plant fossils was found by another person I used to know in the Sydney Basin. I assume it is Triassic, as the vast majority of exposed sedimentary rocks in Sydney are of that age, although it might be Permian. I do not know the exact region. There seem to be multiple different plants on the slab, and they seem to be more poorly preserved than the shale layer plant. Does anyone know what they are? Also, do any of you have any tips for getting better images? If I take any more, I'll probably use my SLR camera, as my phone's camera is terrible. Thanks for the help! Edit: Changed the title to make it more obvious this is a new thread.

Psittacosaur9's Cabinet Renovation Fossil Identification - Mesozoic and Cenozoic Animals Thread
Psittacosaur9 posted a topic in Fossil ID
Hello everyone, and I hope you've all had a good day. I started to put my display cabinet together today, and after an exhausting day of work, I'm only half done and I haven't even started on the bookshelf! Yay! Sarcasm aside, I've got some more fossils I would like identified, as I am creating labels for my displays. Just as before, I would prefer the most specific identification possible - species would be preferable, but I would rather a genus or clade name over an invalid species name. Location would be helpful too. Again, if any of you want them, I can take more photos tomorrow. Specimen 1: Actinopterygii This specimen I purchased at a museum, which simply labelled it as 'fish fossil'. While I do not know the location, I suspected it was from the Green River Formation in Wyoming, as many commercially available Actinopterygii fossils come from that site. At first, I thought the specimen was Knightia, as that fish seems to be one of the more common from the Green River Formation, and the only common one of the same size and rough shape. However, after recently observing a slab of Knightia at a museum, I began to doubt my initial identification, as the Knightia in the museum looked more bloated than my specimen. Is it a Knightia, or something else? Specimen 2: Ammonite I apologise for the rather shoddy attempt at editing out the supplier's logo. As you can see, I purchased this ammonite in a small plastic case at a museum, and cannot take a photograph of it from all angles. However, the back of the box (or at least what survives of it) says that the ammonite is Jurassic of age and comes from Madagascar (thinking about it, the supplier probably had to stick the ammonite to the case in order to get it through customs). Therefore, after comparing it to other ammonites from the same location, I believe it is most likely a Phylloceras specimen, as those ammonites lived in the correct place at the correct time, and had the same shaped, relatively smooth shell. Do you all agree with this conclusion? Specimen 3: Gastropod Another specimen I purchased from a museum with no knowledge of its original location or age. Unfortunately, I know very little about Gastropods, so I do not know how to identify it. Do any of you recognise at least what group it came from, or even tell its species, time period or location? Specimen 4: Ray tooth I received this tooth as a gift in a set of various teeth from Chondrichthyes. The gift set identified the ray tooth as Jurassic in age, however gave no further information on the specimen. To add to the confusion, all of the fossil ray teeth I have found available to purchase online come from Myliobatis, a genus which only evolved in the Cenozoic. While I am pretty sure it is Myliobatis and the gift set's information was simply inaccurate, I would like confirmation that this conclusion is accurate. Also, I do know that there is only half of a tooth; it broke a while ago and I no longer have the second half. Thank you for all of your help! Next up will be a couple of Triassic plant fossils, and following that will be some fossils I am concerned are fake. Hope you all have a good night!- 21 replies

Psittacosaur9's Cabinet Renovation Fossil Identification - Palaeozoic Thread
Psittacosaur9 posted a topic in Fossil ID
Hello everyone! Hope you have all had a good day. I have just finished a long day of work; clearing out my old display case and bookcase, photographing my specimens, carrying my new cabinet and bookcase up from the garage. Now, I am going to post some photographs of Palaeozoic fossils I would like identification of. I will send the other fossil photos later. For any of these I would like the most specific identification possible, as I am creating labels for my fossil display. Sorry if the lighting is poor. If any of you want them, I can take more photos tomorrow. Specimen 1: Calymenid I obtained this Calymenid Trilobite from a museum. I do not know the location, although due to the large volume of commercially available fossils from the country I would suspect Morocco. I initially believed it to be a specimen of Calymene celebra, due to the shape of the cephalon and the bulging eyes, but found out that in Morocco the closely related Felxicalymene is more common. Are there any noticeable distinguishing features between different types of Calymenids one of you or I could identify on the fossil specimen? If anyone has a guide, it would be very helpful. Specimen 2: Goniatite I obtained this Goniatite from a museum. Seeing as the museum described it as coming from the Jurassic, I wanted to double check their identification, as Gonitaites were only present in the Palaeozoic, and after cross-referencing the specimen with online images, I am pretty sure it is a Goniatite. The museum's labels stated the specimen came from Madagascar, but the fossil seems to be most similar to Goniatites from Morocco. What are all of your opinions on the fossil's identity? Specimen 3: Orthocone I do not remember where I obtained this Orthocone from, but I do know it came from Morocco and that I bought it as 'Orthoceras. However, the exact taxonomy of Moroccan Orthocones seem to be in a bit of a mess, as Orthoceras was a wastebasket taxon, and is now considered to only be found in Europe. Different sources have identified Moroccan Orthocones such as this one as 'Arionoceras' or 'Orthocycloceras' (the latter name in particular was used in the 2021 DK Fossil Handbook). Which one would be the more appropriate name? Or is another name more valid? Thank you all for your support! Tomorrow, when I find the time, I will post some Mesozoic and Cenozoic animal fossils, Triassic plant fossils and some fossils I am concerned might be fake. -
Hello everyone on the forum, and I wish you all a good day. I am Psitaccosaur9. Currently, I am renovating my display cabinet, and am going through and organising my fossil collection. Tomorrow or on Friday, I plan to post photographs of a bunch of fossils I cannot classify, in the hopes of getting an identification for them. Before I post, I just want to ask 2 questions: 1. I have quite a few fossils, so should I post them all in one thread or on multiple? 2. I do not know the location of some of my fossils, but I do know the dealers for all of them. Should I post where I obtained them? Thank you for your help. Yours sincerely, Psitaccosaur9

Found this mineralized tibia at the Zandmotor beach in the Netherlands. This beach is known for Pleistocene fossils. I don’t know much about rodents, but it was suggested to me that it might be Arvicola amphibius. It is probably a bit too large for mouse or mole. I would love to hear thoughts/suggestions on what it might be.

Hi all - I found this fragment in Central Texas today, Austin area. Likely Cretaceous or Pleistocene, I think. Is it a bone or something else? Any ideas? thanks!

Hello all. I was hoping someone would be able to help identify this tooth. I've been shelling for years, however fossil hunting is becoming a new and exciting passion of mine. This was found a couple of months ago on Holden Beach in North Carolina. Any feedback is greatly appreciated. Thank you in advance for your time.

I visited a creek that connects to Lake Ontario, and I found this rock. The black area looks like some kind of imprint to me, and more specifically a flower or leaf - but I really have no idea. Maybe coral? I did find a beautiful rock with crystallized favosites coral there too. Does this look familiar to anyone?

I don’t want to say more about the specifics of the location quite yet- i’d like to actually make sure this place is a fossil bed, and that this one find wasn’t just a fluke. I also have to talk more with the land owners, ensure they’d be okay with the site becoming publicly known, as well as work out if they are okay with me doing some more extensive searching and digging in the bedrock. But nonetheless, i wanted to share the find itself because i am so so so happy, as this is my first fossil (and potential site) that i’ve ever found by doing my own geological research, and i wanted to share it here. I hope once i speak with the landowners more, as well as find at least one more fossil to confirm its not a fluke, i can get permission to post the location!

Finished a fossil hunt at Big Brook, NJ! Need help with some ID.
75millionyearsago posted a topic in Fossil ID
The first images are of a bone i am almost certain is non-fossilized but i could always be wrong! can anyone ID the species? Next images are of what i assume may be petrified wood, any chance it is? Its quite heavy for its small size, and has a wood-like texture. Then i have this black shell-like thing, unsure of it’s species but it is certainly something. Lastly i ID’d this tooth as a cretaceous thresher shark tooth- am i right? thank you for your help!- 9 replies

So I found this today… I originally saw the hollow end and thought sloth tooth. But the side where the chewing surface would be is devoid of the enamel ring. However I’ve certainly seen sloth teeth that are worn down enough that the enamel is missing. However it looks like there’s enamel on the broken/hollow/supposed root end - a very thin layer though. The hollow end also has growth rings like a shark vertebra, and with the indent down the side, also points to vert. But it’s only on one side, not the other, which is smooth. That same indent also seems to rule out rib bone, as far as my experience with said rib bones go. So… anyone have any ideas? @Shellseeker @digit @Brandy Cole @Harry Pristis Broken/hollow end: “Chewing surface”: Sides: Growth rings: Enamel?

Hi all - I found this in a creek in Central Texas. Looks like a rudist to me. There’s a good amount of detail visible on it, so I was wondering if anyone might be able to ID it down to genus (or species)? Thanks so much!

Hi all - I found these two pieces in Central Texas today. Anyone have any ideas? The first one looks like some kind of bone, the second looks like some kind of oolitic sediment or possibly a fossilized scute (according to google image search). I could also be way off on these. Any help is appreciated. Thanks!

So digging through micro matrix from the peace River this morning, and I came across this incredibly tiny mammal tooth. Using prior knowledge - 3 roots (2 missing, but still has the holes for the roots), with 1 root being thicker implies this is an upper premolar tooth. Short crown height so it’s from a senile animal. The chewing surface is similar to rodent teeth, but I’ve never seen a rodent tooth with roots. Could this be mouse? Bat? The size is incredibly tiny. Chewing surface about 1-1.5x1-1.5mm. Height including root about 2mm. @MarcoSr I know you picked through some Florida micro with lots of mammal stuff - any insight? @Harry Pristis @Shellseeker @digit maybe you guys can help as well? Apologies on the terrible pics - still struggling to get good pics with something this small!

My son found this in northwest Arkansas. I'm certain it's a common fossil, but multiple Google searches and a reverse image search yielded nothing. He really wants to learn about it, so I thought I'd post here. Thanks, in advance!

Found this tooth in my micro mix - it’s about 1-1.5mm long. Has a cusp. Is unbroken (Except maybe missing a cusp on the other side??) but looks like symphyseal lemon shark teeth roots I’ve seen… got no idea! @Al Dente @hemipristis @MarcoSr

Circular (possibly spherical) Fossil ID Request - Caledon, ON, Canada
QueenCoeurl posted a topic in Fossil ID
This mystery fossil was found in a rock pile in the Caledon, ON area, not far from the Niagara Escarpment. When I split the rock, it was revealed and split into convex and concave halves that then fit together. It is almost perfectly circular, and is 13mm (0.51 inches or just over 1/2 inch) in diameter. There are clearly many other fossils within this rock, but I fear splitting it further and destroying this mystery fossil without ID on it first. I've taken it to a few other hobbyists I know in person, but they has also been unable to ID it, and the best guess I've received is that it some sort of Brachiopod. I remain unsure, as there are no ridges or grooves, and the edge is very smooth. Also the closest looking brachiopod species I could find was the "Obiculoidea" which is normally found in the Texas to Ohio areas. Since the fossil is "bisected" perpendicular to the rock layers, I've had the thought that it could be a cephalopod (some sort of orthocone?) shell, but can't find good cross section images of such fossils that look the same. However the smooth-ness, central void, and convex & concave split would fit what I see from cephalopod fossils cut open length-wise. Let me know what you guys think! -
I found these on the beach in The Netherlands. I would appreciate if someone would tell me if they are fossils or just rocks and what they are, if fossils. In the case of the sand dollars, I don't know if they are skeletons or fossils. They are hard and I can't break them. Thank you so much!

Hi all, me again, I wanted to share a closeup of the bone fragments that I found in Ramanessin to see if I could get them ID'd further since I know how the brook tends to make fake fossil bones i want to check that the ones I found are real fossil bone 1) the big one, i think it might be a cretaceous turtle shell, it passed the burn, and the lick test. 1A) I believe these are also enchodus jaw fragments. 2) 2A)

Stick around, this one's a read but I'll try to make it fun. So, I have been to big brook last year, and While I enjoyed it, since I went in early feb, the ground was frozen which prevented me from finding much, as the brook was stingy that day. Nonetheless I decided to try my luck with Ramanessin as i heard good things about it. Because none of my family or friends could be bothered, I decided to take a day off work and drive 4 hours to the area and spend the night so I could get the most out of the location. what follows is the result of 2 days straight of fossil hunting. which I will try to tell the story of in order. Day 1 the scoop I arrive at the site a little past 12, choosing to waste no time, I make my way down to the brook and start to sift the gravel. as opposed to when I went to big brook in winter, Ramanessin was generous with her gifts. I found 4 teeth in the first scoop. I took this time to make my way up the stream cutting back and forth sifting every gravel pile I could find. my personal method is to put no more than 5 scoops into the sifter. that was the way to guarantee I got at least something out of it. it was during one of these sifts that I found the curious reptile tooth here. I will be doing a separate fossil id post later of the teeth and bones. but this was one that i knew was something special. I also found this really nice cross section of ammonite. the sutures were beginning to separate, any longer and they would have come undone. It was also this trip that I found these chunks of bone, now I know the brooks have this nasty habit of producing concretions and discoloring modern bones to Look like fossils, but i am 80 percent sure that I found some genuine articles here. Taking the ###### at some point in this day, I decided I needed to pee. so, to avoid being spotted I ducked into a small mouth of a tributary to do my business. while I was wrapping up, something caught my eye, something I couldn't believe. the outline of the Biggest, and likely one of the best lateral goblin shark teeth I have ever found. I was absolutely giddy. after picking it up and doing a little field prep washing it off in the water it was easily 1.8 in. and as the story usually goes as I am looking in this little alcove of gravel, I see the root of yet Another massive goblin tooth root, this time submerged in the dirt. I chanted to myself "please be whole" as I carefully brushed off the tooth to reveal a gloriously intact fossil. easily one of the best and most fortuitous pee breaks i have ever had! It was on my way back that I decided to put the trash bag I brought to good use and pick up the garbage I saw on the way. I'm not going to lie here, I have found it pretty shameful how many shards of glass and cans I would find in this place. But I took it upon myself to fill the shopping bag as best I could. I didn't want to be stuck out in the dark, so I hurried back to the car and dropped the trash in the nearest bin. Lodging back at the motel, I spent the evening cleaning off my newfound loot. I took this time to carefully superglue the ammonite chunk so that I wouldn't lose it. I took one of the plastic cups in the hotel room and cleaned my fossils with it. Day 2 lost sifter After breakfast, I returned to try my luck again, but when I opened the trunk of my car I was met with the absence of my sifter. I t was then that it dawned on me that when I came back to the car I had only my shovel and my trash bag in hand, tricking my brain into thinking i had everything! realizing it was probably lost, I went back to the brook to try my luck surface collecting. The region had received some rain overnight and into the afternoon, and although it wasn't flooding, the water was considerably higher than last time. i was almost discouraged until i noticed something bright blue on the opposite side of the brook... it was my sifter. right where i left it on the top of the overbank. I was so elated I was laughing at my turn of luck. "Hang On! I'm comin!" I yelled at the inanimate object. there was a fallen tree 4 meters from the sifter, so in my full wading gear, I straddled the trunk and shimmied over to the other side and retrieved it. mosasaur it was now that I decided to make my way upstream and sift past the areas that I had already hit. I noticed a few tracks of bootprints here and there. I was initially discouraged by the fact that whoever it was got further than I was hoping they did. but that all went away when as I was sifting through a pile of gravel, I noticed a sheen of blackish enamel. picking it up I realized this was likely yet Another reptile tooth, and the chances that I bagged a mosasaur had effectively doubled. (did I mention yet that this was my 1st time to Ramanessin?) check your spoils as I made my way upstream, I came across the ruins of some old concrete structure in the middle of the brook, either a dam or a bridge foundation of some sort. to my right I saw a large spoil pile. out of curiosity, I started to look at it trying to see if there was anything the previous person missed. and boy was there. I found another huge lateral goblin, and (Pictured separately) a massive sawfish rostral tooth. it was crazy to me thinking about missing not one, but Two easily trip maker sized teeth in your spoil pile. let this serve as a lesson to newbies, to double check spoil piles you see, just because you never know what the last guy missed! crow island I waded and sifted my way upstream past the concrete structure, tactically using my shovel as a sounding stick of sorts and pointing my toes in the direction of the current so as not to lose footing. I stopped just past a footbridge where there was a little island of gravel that had accumulated over the weeks. as I scanned the shore, I saw another trip maker: an absolutely huge Squalicorax prisodontus tooth. it is at this point that I notice that I want alone, there was a group of boys that went bicycling overhead. now, all through the day I was completely alone, talking to myself about the stuff i was finding and being a general silly guy. I'm sure that if anyone came up to me while I was like this, they'd think I was insane. I took this brief encounter as my sign to start heading back to the car. the wade back the wade back I made it a resolution to not sift bit surface collect only. the thing is, that in the hours between when I got there and now, it had stopped raining. and when the rain stopped the waters started to recede after an hour or two. So here I was, walking back to the car past effectively virgin shoreline, with only an hour of sunlight left. I was delaying myself left and right with tooth after tooth that I would find on the shorelines. some being decent sized in their own right! after I returned home, I spent the remaining hours of my sanity cleaning and sorting the finds of the day. this is the total finds for day 2. Aftermath below is the combined total of fossils. of the identifiable items I found approximately 234 goodies over those 2 days. my display case for Cretaceous NJ was looking a little sparse before, but now its looking a little fuller as I am writing this. if you notice any special things in the pictures I missed, please let me know, I love educating myself on these things.
