Hello all! I found this today and originally thought it was an archaeological item, I sent it off to the local officer and he said that he thinks it's a sponge fossil. I was wondering if anyone may be able to give me some more information please? Thankyou!

I found this piece and several others this past weekend. This is one of the smaller pieces, roughly 15”X9”X7”X2” thick. Please take into consideration my lack of fossil cleaning skills. It was found in the Hill Country of Texas, Bandera County.

Found in a wash of an Upper Cretaceous formation in the Four Corners area of the United States. I guess it is some sort of fossilized egg but would like a second opinion. In the formation, fossils from former terrestrial, aquatic and arboreal life is routinely found. The specimen is 6.3 cm long, and due to some compression at the time of fossilization is sort of shaped like a Brazil nut around its middle.

Hi everyone, I hope you're all having a good start to 2021. Tonight I'm sharing a fossil which has been in my possession for a number of years. I found it on my first trip to Big Brook in Monmouth County, New Jersey when I was only 11. Some veteran fossil hunters took a look at what I found and told me it was a dinosaur bone. Being a novice I took their word at face value, however after a number of years dinosaur hunting out west, I was able to see that this ID was incorrect. When I showed it to a paleontologist at my local university he did not think it was bone at all and perhaps some plant material. At this point, however I am confident it is actually bone, and most likely from a marine reptile. An interesting comparison I made was with a piece of dugong rib I found on Florida's Peace River. I found that both were quite dense, with small outer pores and minimal spacing in the cancellous tissue (especially when compared to true dinosaur bone). Additionally, the presence of apparent bite marks suggest to me that this is not a concretion or plant material. The fossil is about 6.4 cm in length and 2 cm in diameter. I would like to hear some opinions on it. Thanks, Noel A close up of the bone surface. The quality of the photo was not what I had hoped. Closeup on one of the apparent bite marks.

Hi all, I made my first trip out to Ramanessin Brook (NJ cretaceous) today. I found several teeth, and a partial shark vert. I also found what is most likely a rock, but might have some impression in it, and a partial bone(?) with nubs and grooves. If anyone can help with either I appreciate it. I took an overall photo of each, and then close ups using a jeweler's loupe. If the closeup photos are not adequate enough I can try to take better photos. I have a decent mirror-less camera, but I don't have a macro lens for the closeups. The light piece is probably just a rock. But the dark piece appears to be something, fossil or not. Thanks! Steve

These are two Hadrosaurus jaw fragments I’ve had for awhile. As far as I know they are from the Hell Creek formation of Montana. I think they might be Edmontosaurus but I really can’t tell. The fragment exhibiting tooth channels is about 8 inches in length. The other fragment or chunk exhibits many broken teeth and is about 4 inches in length. @Troodon @jpc might like to have a look?

I found this fossil at the Molecap Greensand Formation in Western Australia. It's a Late Cretaceous coastal marine deposit, mostly marine invertebrate fossils there, shark teeth too. Sometimes marine reptile fossils and there's also been a couple of dinosaur bone fragments found, plus a pterosaur jaw fragment. I visited there in search of shark teeth, unfortunately I didn't find any but I did find whatever this is. Maybe a bone fragment of some sort? A rib fragment maybe?

(?) Walnut Fm, near Kerrville, Texas -
see previous picture. (?) Walnut Fm, near Kerrville, Texas -
This came out of a road cut on IH-10 near Kerrville, Texas. From a thick marl bed that I think is the Walnut just above the Glen Rose Fm. -
Bottom is from the Upper left of the first image. These were found at an outcrop of the Upper Glen Rose just south of Comfort, Texas -
Found south of Pipe Creek, Texas, and north of Medina Lake. -

Hello All this is a wrap up of our finds from our Richmond trips 2020 This post is about two trips combined where I visited the same location which is Richmond , NW Queensland Australia. The dig site is a public dig area which contains Cretaceous marine material from the Toolebuc formation. This site is well known for its abundant fish, shark ,marine reptile bones and rare bird/ pterosaur fossils. Growing up in the North Island of New Zealand and I have been collecting fossils since I was a kid however fossils from vertebrate animals are exceedingly rare in that area (Except Shark teeth) therefore my knowledge of vertebrate fossils is very poor. So, going out to Richmond which has abundant vertebrate fossils is a dream come true I have learnt so much over the last 3 years heading out there. The first trip was in July which I did with my partner and kids and the 2nd trip was in October which I did solo due to the extreme weather at the time. Due to the weather which was 42C and threat of severe storms I located the area I wanted to dig and did most my work at night with lamps, there were also less flies at night which made it more pleasant. During the two trips we found several turtle bones which was exciting and unexpected, it wasn’t the kind of marine reptile bones we had in mind. We found a small ichthyosaur tooth and a neural arch. There are layers of material known as fish mash which contain large amounts of small fish bones. Amongst this we found a few larger fish bones and a fish tail. My partner also found the largest and first sharks’ tooth of our trip she was very happy about this. We collected some of this material which we took home and broke up and sieved for shark teeth and any other rare or unusually specimens. Working alongside my 11 year old son we broke up and processed the fish mash material where we found a few smaller turtle bones and sharks teeth our best finds were 3 johnlongia teeth these are usually rare so we were good finds, the third tooth which he found he was able to ID the tooth which was great to see how much he has learnt. Also goes to show how much better his eyes are than mine as I missed it. Lastly, I would like to thank everyone on the forum who has given me advice and helped me ID fossils especially Mike D’Arcy without your help we would of never made these finds thanks a lot mate. Cannot wait to get back out there. Finding the dig site before dark, yes the silly looking mask is required to keep the flies out. The dig site at night. My wifes tooth. I will put more pictures in comments

Hello, I went on a walk a few days ago to the local chalk pit and of course couldn't resist spending a few minutes scouting for fossils. This is one of two specimens that I found, the other being a shell fragment. At first I thought the pattern might be formed by ice but I wasn't convinced and kept searching, managing to recover two other small pieces. My suspicion of it not being ice related was confirmed when at the bottom of the slope I found the more complete counter slab, with a layer of ice still covering part of the fossil. Needless to say this made for cold hands on the walk back but I wasn't going to leave it. And an enhanced version of the positive using RTI. If I had to guess what it is I would say bryozoan but I haven't hunted the chalk much before and don't know. The fossil comes from the Upper Chalk and is Turonian in age. Hopefully someone has a better idea what I've brought back. Thank you, Benton

Hello everyone! I found this yesterday in a Cretaceous stream in Monmouth County, New Jersey. It measures 3/4th of an inch long. I was thinking Hadrosaur but I've never seen one this thin so I figured I would look for some other opinions. As always, all help is greatly appreciated! Frank

I was fortunate enough to find many nice teeth during 2020. These are some of either my nicest, favorite, or somewhat uncommon finds from my searching at Big Brook, NJ. These finds are late cretaceous (~65 million years old). Sources for identification: http://www.njfossils.net/cover.html Fossil Shark Teeth of the world, by Cocke The first picture are 4 of my largest and most complete goblin teeth (Scapanorhynchus texanus), all found on the same day! I think it had rained overnight, though there was no rain in the forecast. I think this along with unseasonably high temperatures led to bit of erosion. Picture #2: Mackerel teeth Left to right, first is Cretolamna appendiculata (lata?) and the latter two: Archaeolamna kopingensis. Mackerel teeth are some of my favorite due to their shape and cusplet size. Picture #3: A branchial tooth from an early drum fish (Anomaeodus phasolus). More photos will be uploaded in a comment.

From the album Dinosaurs
Species: Spinosauridae indet. Age: Cretaceous (Cenomanian), c. 95 million years ago Location: Kem Kem Formation, Morocco Probably the most common dinosaur fossil available on the market, a Kem Kem Spinosaurid tooth. At least two spinosaurid species are known from Kem Kem; Spinosaurus aegyptiacus and Sigilmassasaurus brevicollis. As there are no known teeth of Sigilmassasaurus, comparisons between the two are impossible and determining the genus which the tooth belongs to is also impossible. -
From the album Dinosaurs
Species: Tyrannosaurus rex Age: Cretaceous (Maastrichtian), c. 66 million years ago Location: Hell Creek Formation, Montana, United States Quite small tooth fragment of a juvenile specimen (classically referred to Nanotyrannus, now no longer recognized as a valid genus), but serrations are preserved. Identifiable down to the genus and species level since Hell Creek did not have any tyrannosaurids other than Tyrannosaurus rex.
