I’ve made several trips to Greens Mill Run recently, lots of shark teeth and belemnites, large intact scallops and clams, large whale ribs and jaw bones and ear bones. However I have 3 fossils I cannot identify. Some pics are below: The top tooth is either mosasaur or crocodile, not sure which. The other two, I’m clueless. Any help would be appreciated!

I was out today with a friend hunting the Peace River. You might ask how. 90% of the river is way too deep and dangerous to hunt. I have a temperamental back which does not allow me to hunt areas that are less than knee deep. During season, there are many isolated areas like that, and for likely places we dig probe holes to determine if the area contains fossils. We identify areas which might be hunt-able when the river is 4 feet above normal. So a lot of small shark, ray teeth, mostly broken and a few finds that make the trip worthwhile.. On this day, a posterior Meg, a chunk of antler, and an unknown. The unknown is definitely a fossil, but what... a Ray barb tip, a Bill fish tip, could it be a tusk, fossilized wood..... I need help... Thanks for any suggestions and comments... Jack

With the River and creeks WAAAAY over my head, I have started to sort, review, reduce my collections from the last 3-4 months, starting from the most recent. I have a couple of interesting bones. The 1st I think in a cannon bone from a small pre_equus horse. Why small pre_equus horse? I find 1 Equus fossil at this location for every 100 pre_Equus horse fossils, plus this bone is too small to be an Equus cannon bone. Why Cannon bone ? Because it seems very similar to a photo of Equus Cannon bone created by @Harry Pristis. Harry identified as left leg, Mine seems to be the opposite oriented for a right leg. Metacarpal is the foreleg designation. How can the metacarpal be differentiated from the metatarsal (hind leg) that seems very similar? My find: Not impressive in this 1st photo. There are some differences with Harry's photo above, but I can not imagine what else it might be....

An Interesting bone, It does not seem to be predator, so I am thinking something like Tapir, Peccary, etc. My biggest concern is that I have found pre_Equus horses, Gomphothere at this location and very little Pleistocene mammal material. But we will see. It seems to be the size of and resemble Tapir toe bones. I have copied one of @Harry Pristis excellent charts from another thread... Does it not look like a tapir phalanx? Comments greatly appreciated. Jack

Hi Guys and gals, does anyone know what jaw bone and teeth this belongs too? its upto or around 2million years old and is from java indonesia, found in the same deposits as stegodon, hippo rhino, bison and so on.. i just can't place it, some better photos of the teeth would help but i don't have them yet... many thanks
-
I have this bone that I found 4-5 weeks ago. I have not had any new insights, but I think it strongly suggests marine mammal and because of the foramena, mandible. All suggestions and comments welcome. Jack

Went out again yesterday (It's easy because I am retired,and planned to prioritize fossil hunting). It has been a while since I hunted here, and my friend and I commented that there had been intensive hunting since we were here last. While he was doing pretty well on Megs, Makos, and Hemis, I was having trouble finding a productive spot. -- it happens. The day was overcast and hot, but I am standing in water feeding the swarms of mosquitoes and an occasional horse fly. Did someone ever tell you that "Deep woods Off" would keep these varmints from pestering you? I have a not so secret strategy: Sink into the water covering the hairline on the back of my neck and up to my lower lip. Then I attempt to eat the mosquito that flies under the brim of my baseball cap to land on my nose. This is not particularly effective, but I enjoy trying to make them pay for my blood. It does distract me from fossil hunting, but they were doing that anyways. I always find a lot of small shark teeth, usually broken and fragments of bone and mammal teeth. This time about 150 of which 80-90% are broken. Here is what is left, after 5-6 hours of hunting. Most of this is marine, 10 shark teeth, 5 Ray dermals, pufferfish mouth plate, a couple of Ray barb fragments, and sawfish rostral tooth across the top. The only mammal is a chunk of Gomph enamel at 11 o'clock. I like the best Ray "button" dermal and smaller Sand Tiger.. Those are keepers. But, my find of the day is a broken 32 mm marine mammal tooth... I am easy to please. I love the enamel rugiosity because I do not find enough of it. Enjoy,

Hello! I found one yesterday that's stumped me. I've used the NC fossil club book and the Google and I've not seen anything like this. The smoothness of the upper part is throwing me off as the other whale teeth I have are textured. Same with the crocodile. This was found in NC where the Pliocene Yorktown and Miocene Eastover are exposed. I can take measurements later if needed. Thanks in advance!

Hi, Mi names is José. I from Piura, a city in the northwestern cost of peru. Together with my friend we find this shark teeth fossil in marine terreins of upper miocene - pliocene in Sechura basin, very similar to Pisco Basin (that may be better known to you). We need help to identify this teeth and others too ( https://drive.google.com/drive/folders/1F6O3ql4zvtRnShPd0ZoOVWJ6tPbOimgr?usp=sharing ) Y1_50 3 --> Isistius triangulus ¿? Y2_328 --> Carcharocles Megalodon ¿? Y1_305 --> Carcharhinus sp ¿? Thanks and sorry for my bad inglish grammar.

Hunting trip to the Peace River. This is my day "job". The weather is very hot... mid-90s Fahrenheit, little breeze. It is very nice to be standing in a river. With the sun bearing down, I frequently submerge to my chin to cool off. We anticipate afternoon thunderstorms to roll in and soak us. Sometime thunder and lightening add to the experience. Usually there is insufficient time to reach cover before getting drenched. Sooner or later we'll get enough days with thunderstorms that will refill the river from its current low levels. Today is a sorting and photo taking day, when I get to sort, inspect , evaluate my finds, decide what to keep and what to give away. I have already removed the small shark teeth and bones that I donate to schools, fossil clubs, kid's digs, and friends. My wife's goal, after 12 years of this hobby, is for me to keep as few as possible. This has been a magical season which continued yesterday. Here is my final sort... with a couple of hoof cores, a couple of horse teeth, an earbone of a deer , I think, odd looking, almost complete bones that I'll try to identify, and my find of the month, a 70 mm Ursus Americanus Canine. I usually gussy up my fossil finds for their coming out photos.... here are some. The upper hemi is 41 mm, I love the serrations. I find many of the upper roots broken off. Nice to find one attached. A giant Tortoise claw core. This is a first for me. Maybe I just never recognized them. or thought they were a hoof core from some other animal. This one is a Bos or Bison hoof core. It is small at 2.8 inches, so more likely Bos, but not sure anything is deterministic. Small upper horse teeth. The 1st is 26 mm APL and almost seems to have an isolated protocone and the 2nd is 20.6 mm APL and the protocone area is broken away . Then the bear Canine at 70 mm. I think it is lower because of shape and right because of wear facet from upper canine. Certainly is a great memory and a trip maker. It is my 3rd (others in 2012 and 2017). I found it early about 9:30 am. A great day, good friend, the skies opened up around 2:30, a little Thunder but no lightning (at least none close) for these fools standing in the river holding lightning rods.

I was out hunting today.. Gorgeous. Sun shining, middle 90s, cooled by the Peace River. I need to investigate a small vertebra and what seems to be a fish tooth before asking for IDs. But for this thread, a slightly broken molar that seems like it came from a predator. I do not have accurate size measurements, but judging by the size of my fingers, the length of the chewing surface and the crown height are both approximately 1 inch.

Hello All, A friend of mine recently sent me some fossils he found near his home in Florida. It was suggested to us that they were from the Tamiami Formation, from the Pinecrest Beds. I’m relatively new to the paleontology of Florida so I have no idea if this is correct. I’m hoping that the community might be able to help identify some fossils. I apologize in advance for the quality of some of these photos. Because of the coloration, getting clear shots was sometimes difficult. I’d be truly appreciative if, along with the name of the fossil, you could include the citation from where you found it, if possible, as I would like to start building up a bibliography of Florida fossil resources. All fossils were taken from spoil piles and surface collecting around building sites in Manatee County, Florida.

I went out hunting today in the Peace River and found some very nice fossils, which were unusual for the Peace River. then this... A 54 mm Canine. I showed it to a couple of people, who both responded "likely seal". I searched the internet for fossil seal canines. Take a look at the enamel tip. It is distinctive! However, all the fossils identified as Seal Canines have tips not remotely similar to the one I found. What am I missing ? Also , I thought about the age of this fossil. Just by sea level measurements over the last 20 million years, we know that there has been no salt water over upper Bone Valley for approximately 3 mya... that is the Pliocene. Callophoca obscura is included in the "Palmetto fauna list" dated 4.5-5 mya as early Pliocene. So, Is this a seal tooth? Can we determine lower jaw , left or right.. Are there other possible candidates in the Florida fossil record besides Callophoca obscura ? Are there other seal candidates in Southeast US? I love a good mystery. @digit @Harry Pristis @Boesse

I just ordered this piece which I was watching for quite a while as I wanted to add some more bird material to my collection. It's a penguin beak found in the Bahia Inglesa Formation, Atacama Desert, Copiapo, Chile (Pliocene, around 4 mya). It was listed as "Pelecyornis sp." but since that is a genus terror bird I don't think that ID is correct. After doing some google research I am more leaning towards perhaps Spheniscus urbinai or Spheniscus megaramphus or another species. But I am far from an expert on bird material let alone fossil penguins so I was hoping on some imput from more experienced members on that field.

One more. What throws me off about this one is the oval root base, when all several dozen other Odontocete teeth have a circular root base, and the wear pattern on the tip. Thoughts?
-
hello everyone, I am looking for some assistance in identifying two odontocete teeth from the Pliocene Yorktown Fm, Lee Creek Mine. The first photo shows the two teeth in question on the left vs a Kogiopsis sp. tooth on the right Are the teeth in question just Kogiopsis with the crunchy outer coating intact? Marine mammal ID isn't my forte. There are 3 photos each. Interesting that the second of these teeth almost has an opaline filling of the basal cavity. Any help is greatly appreciated!

A couple of weeks ago I was in Southern Florida with my wife and my sons family for 8 days. My wife, my 7 year old grandson and your’s truly. During this time I was able to get out and collect fossil Pliocene-Pleistocene shells from the Caloosahatchee Formation. Collecting fossil shells is one of my favorite fossils to collect and I love it when I find complete examples. I have been to the Peace River a couple times, and even stopped there on the way home to take a look at it, it was very shallow, there was a group of people sifting, but I did not partake. I do enjoy collecting fossils from the Peace River, but I would rather collect fossil shells. During this trip I did collect hundreds of fossil shells, but I am only posting a few species of complete fossil bivalves, some of these have predatory drill holes in them. @MikeR hopefully you can let me know how my identification is on the following shells, I tend to mess these up. Eucrassatella speciosa Chione elevata Arcinella cornuta Plicatula marginata Carditamera floridana Same as above- Noetia ponderosa macnelli Lucina pensylyancia Solecurtus cumingianus Arca wagneriana Dosinia elegans

This was found between glacial and non glacial quaternary sediment. Slightly north of Ocean shores, WA. NOT on the beach, but where the forest meets the beach and erosion is occuring. I brought this to the only fossil shop local to me and all they recommended bringing it to another shop hours away so trying my luck here! You can see the vertebrae which after taking a soft brush to curves around in the shape of a I, the clearly visible vertebrae at top are the largest in with, however the length of each remains the same as the width lessens. There are at least 9 vertebrae I can count. The width starts at .25", there is 1" of vertebrae exposed prior to curving back up, 2" total exposed vertebrae. Curious if where it starts curving are joints? You see in pictures where it curves that specific block looks different from the rest. What is your best ID guess? Thank you so much!!!

Hello everyone! I am looking for help to identify this macrofossil sample of a leaf. It shouldn't be older than pliocene. Really struggling to identify it. Thought of it as Nothofagus or maybe Populus. Was looking for it in Zelkova, but nothing quite matches it. Does anyone know or have a suggestions, what it could be? Thanks in advance! Philipp

After a 3 month dedicated search (coughSisyphean) to figure this out on my own, I still can’t find anything that remotely looks like this. I’m a longtime SE LA/SW MS creek gravel rockhounder and I’ve never come across this before. I’ve shown it to some other area collectors-no luck. This was found in a creek running through the upper terraces of the (pre-loess) La Citronelle formation not far from the Amite County, MS border. *I should also mention that Louisiana gravels within the (Plio) Citronelle contain much older rocks/fossils that are believed to have been transported by glaciers, as well as ancient interbraided streams. Frequent flooding subsequently washes these out of the upper terraces. To my eye, though, this piece doesn’t appear to be rounded or very worn. If I had to call it, I’d say table coral/freed piece of reef, but that one side having the appearance of muscle attachment grooves has me wondering about that. I greatly appreciate your time and opinions; thanks for giving this an eyeballing for me.

Many things on the plate. I went back to sort finds from a trip last week and found this fossil that is confusing me. It was late in the day and I was hurrying to empty this sieve and load another one. I thought it might be a mandible section and noting no teeth, tossed it into my collection bag. Now , I am at the point of trying to figure out what is it. It is a Mandibular symphysis, exciting by itself and small .. 16 mm length, 10 mm wide, and 7 mm high. Seems to have 4 or 5 Alveoli pointing straight ahead. like incisors of a tayassuid. I have looked at the Internet but nothing seems similar enough. Perhaps others have seen something like it. I find Blancan fossils at this location mixed with Pleistocene. Thanks for the help. Jack

I have been hunting fossils for 15 years. On Thursday, I found my 2nd ever section of detailed Cetacean jaw material. These are exceedingly rare. It is 2.8 inches in length and has 3 alveoli. It would seem to be more Dolphin size than whale sized. The patina would indicate that the top and 2 sides are relatively complete, and it is broken at the underside. Position wise, this section might be lower right, posterior half of Jaw. Please let me know if you agree this is Dolphin, and what are the possibilities. Here is a photo of Kentriodontae Dolphin with a jaw segment of similar size and lots of teeth !! Please try to give me some insights. Like were the teeth as short as it seems they would have to be to fit this jaw.
