Hey everyone, I have this possible Mastodon tooth “cone” from NJ. I know it is a fossil, meaning it’s got to be Cretaceous or Pleistocene because of the area it was found in, and it really doesn’t look like any Cretaceous bone I’ve seen from here. That shiny inner stuff on the inside (the concave side) of the item reminds me of enamel; it led me to conclude that this is a partial “cone” of a mastodon tooth. I don’t know much at all about mammals, but it appears that the shiny stuff is what’s left of the enamel/cementum/whatever it’s called that would have been on the inside of the cone. That inside part also has cracks running lengthwise and an uneven surface. The outside layer (on the more convex side) of the possible mastodon tooth cone seems pretty worn away and may have had a whole entire layer of enamel covering it before the wear. It’s about 1.5 inches. @non-remanié This possible remain will most likely look significantly different than fragments from other states because NJ’s preservation is usually different. I’m going to tag some members that I think are experienced with Mastodon remains from other states. @Harry Pristis @PrehistoricFlorida @Shellseeker @digit @jcbshark @Gatorman @RickNC Thanks guys!

Camel partial tibia? Late Pleistocene Northern Lithuania
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, Few months ago I found this partial tibia that is 20 cm length and has less protuberant central ridge than auroch or horse. The other interesting feature is oblong shallow pit in the side of central ridge and also smooth surface of plain bone part when horses have horizontal wrinkles of bone and bison or auroch has longitudinal waves in the same surface part. The frontal protuberant ridge, its low height and visible oblong pit in the side makes me think it should belong to camel but the only camel genus of European Pleistocene is Paracamelus that is found in Romania. If anyone knows Pleistocene mammals well and has comparative material, please help to confirm this bone or identify as another taxon. Any help will be very appreciated! Best Regards Domas -
Hi, I found this small fossilized bone, about 6 months ago in southern Galveston Island. I haven’t been able to ID what animal it came from. The geology of the area is from the Late Pleistocene (100,000-11000 years ago) Beaumont formation. I have found fossilized turtle shell fragments, and fossilized crab claws in the same location. It measures just about 1 cm in length and width. Any idea as to what is is? Front side Back side

Hi all, So on Tuesday afternoon, I was lucky enough to only have a half day of school. Seeing that the weather was nice, and that I had nothing else to do except go home, I decided to take the bus in the other direction, so to Kijkduin, in order to do some fossil hunting! I bought a sandwich and a chocolate bar at the Shell gas station, and set out on the beach. From the beach of Kijkduin I walked south, so towards the Zandmotor, while of course looking for fossils. View of the beach (mind that the sea is on the right side, on the left side it's just a small lagoon), with the haven of Rotterdam in the background. View of the beach with Kijkduin, and then Scheveningen, in the background. (Sorry for the blurriness...)

I was digging around in Sacha's wonderful Merritt Island matrix the other day and found this. First let me apologize for the fuzziness of some of the images. My curiosity over-road my patience. Because of the ball and socket, I'm thinking this is a salamander caudal vertebra? If that is correct, would this be a vertebra that would break in an effort to avoid predators? Or could this be where the tail grew back? Mind you, these are just guesses. Perhaps it's not even from a salamander. I will try to get better photos, but this little bugger is so small, I'm having a hard time getting clear images. Thanks for your help! @old bones, @MarcoSr

Dear Guys, I found this 17 cm length bone fragment in the sand dune layers of Varena town, there was the building site where the sand was deeply mixed up with younger layers. Judging by the shape, I think the most correct version should be bear (the tibial plateau is separated and not found). The last brown bear (Ursus arctos) in Lithuanian territory was hunted in 1885 but the tibia is quite big and maybe there are more features that could differ from present bear that is known is the European and Russian forests. Please help to confirm Ursidae family by this bone and if you are able, identify the species by size or other features. Any help will be appreciated! Best Regards Domas

Dear Guys, I have found this bone fragment about 6 months ago and I am not sure which family of mammal it belongs to. It is the lower end of radius, to me looks like similar to carnivorous cat but I am not sure if it cannot be an ungulate. The length of piece is 9 cm. Please help to identify this bone. Any help will be appreciated! Best Regards Domas

Mammoth Tooth - Mammuthus columbi SITE LOCATION: West Point, Cumings County, Nebraska TIME PERIOD: Late Pleistocene - (About 25 thousand years old) Data: The Columbian mammoth (Mammuthus columbi) is an extinct species of mammoth that inhabited North America as far north as the northern United States and as far south as Costa Rica during the Pleistocene epoch. It was one of the last in a line of mammoth species, beginning with M. subplanifrons in the early Pliocene. The Columbian mammoth evolved from the steppe mammoth, which entered North America from Asia about 1.5 million years ago. The pygmy mammoths of the Channel Islands of California evolved from Columbian mammoths. The closest extant relative of the Columbian and other mammoths is the Asian elephant. Columbian mammoths had four functional molar teeth at a time, two in the upper jaw and two in the lower. About 23 cm (9.1 in) of the crown was within the jaw, and 2.5 cm (1 in) was above. The crown was pushed forward and up as it wore down, comparable to a conveyor belt. The teeth had separated ridges of enamel, which were covered in "prisms" directed towards the chewing surface. Wear-resistant, they were held together with cementum and dentin. A mammoth's molars were replaced five times over the animal's lifetime. The first molars were about the size of those of a human, 1.3 cm (0.51 in); the third were 15 cm (5.9 in) long, and the sixth were about 30 cm (1 ft) long and weighed 1.8 kg (4 lb). With each replacement, the molars grew larger and gained more ridges; the number of plates varied between individuals.

Dear Guys, I recently found some bones that are difficult to me to identify- possible mammoth rib proximal end, rhino zugoma and unidentified radius bone in Late Pleistocene sand layers of Varena Town, South Lithuania (it is Eastern Europe). The width of mammoth rib proximal end is 6,2 cm in the articular part, the bone layer in the cross section is massive. The length of possible rhino zygomatic bone is 5,6 cm and it has specific texture in the skull surface near eye. It is also massive and I see that thickness of bone is about 1,5 cm. The partial radius is 10,2 cm length and 3 cm width in the lower articular part. Any idea what this should be? Best Regards Domas

Dear Guys, Today I found very interesting and also simply looking tusk fragment in Varena town (South Lithuania) near my home. Its length is 8,3 cm and it has thick bone layer in the both ends. It is almost straight and by appearance of piece I see that it was long and sharp. The age of fossil is Late Pleistocene, the last glaciation times. Any idea what is this? Best Regards Domas

Dear Guys, Today I found two premolars that are too sharp to Bison in my opinion, so I think they should belong to camel. They are found in Varena town, South Lithuania (it is Eastern Europe). The bigger tooth is 2,4 cm width, smaller is 1,9 cm width. Any idea what is this? Best Regards Domas

Dear Guys, Yesterday I found one big calcaneus bone, I think it should be carnivore because the big joint is located in the side. It should not be an ungulate. It could be the most similar to cat or dog but I think dogs did not have so large calcaneus- my find is 10,5 cm length. Any idea what is this? Best Regards Domas

Dear Guys, I have found the first phalanx bone of artiodactyl in the same forest felling as two calcaneum bones similar to deer. The wild ox and big deer phalanges are very similar but it would be great to know which animal it is. The size of first phalange is 5,3 cm length so it should be small wild ox or big deer (e.g. Irish Elk). Any idea what is this? Best Regards Domas

Dear Guys, I recently noticed the surprising similarity between two calcaneus bones I found in the same forest felling in South Lithuania. I think they belong to deers but the first in the picture is very big (8,3 cm length) and second is small (6,3 cm length). Is it possible that larger bone belong to Irish Elk? The latest fossils of this animal found in Siberia, they are 8000 years old. Best Regards Domas

Dear Guys, I have found one thick phalange but I cannot decide what animal it is. Very similar appearance have mammoth but also horse distal phalange. The width is 6 cm. Any idea what is this? Best Regards Domas

Dear Guys, I found this atlas vertebra 1 year ago in the Pleistocene sand area of Varena town, South Lithuania. By the attributes, I think this vertebra belong to felid. If it is felid, it should be bigger than cat or bobcat. The bigest diameter of it is 5,5 cm. Any idea what is this? Best Regards Domas

Antelope metapodial and calcaneum from Late Pleistocene
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, I have two possible bones of antelopes, they are very small to ungulates. I found these two bones in the Late Pleistocene sand layers of Varena town, South Lithuania. The calcaneum is only 4 cm length, metapodial- 10,5 cm length. The confirmation of these fossils would be very helpful to my further articles. Any idea what is this? Best Regards Domas
