Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the ot

Trying to figure out what this is a fragment of? It appears to have an enamel coating but I’m not familiar with mammal teeth….possible tapir tooth fragment? Found on Amelia island!

I found this maxilla piece on the Kansas River today. I'm thinking it's some sort of pig ancestor, and hoping it's not just an old domestic pig's. But it seems mineralized to me. Also, the teeth are pretty worn so it's hard for me to ID them. I saw this topic And thought it's too difficult for me to ID based on the worn teeth. But maybe someone else here can help? Please let me know if more photos would be of use as well. Thanks in advance.

I think I already know the answer here but what are your thoughts on this humerus. Found in a creek bank in southern Minnesota. Sediments in the area range from cretaceous to holocoen with a good amount of Wisconsin lobe glacial till. Previously we have found bison, mammoth, and ancient horse...

I found this large bone at the Kansas river today. I believe it's permineralized phalanx and it is about 4 inches long. If anyone can help me out I'd be very appreciative. If you need more photos let me know. Thanks in advance (Apologies for not using centimeters, I couldn't find my tape measure so I used a yard stick. )

Mammoths and other large animals survived in the north much longer than previously believed. New DNA research indicates that the climate, not humans, led to the demise of these large creatures, Norway Science, January, 2022 The open access paper is: Wang, Y., Pedersen, M.W., Alsos, I.G., De Sanctis, B., Racimo, F., Prohaska, A., Coissac, E., Owens, H.L., Merkel, M.K.F., Fernandez-Guerra, A. and Rouillard, A.,2021.

Hello, Earlier today I found these two Fossil vertebra which I suspect are either Fish or Mosasaur or Plesiosaur, in a small gravel bank near some Texigryphaea. These are also my first fossil vertebrae. I found these two in the East Fork Trinity River in North Texas. And the two vertebra were right next to each other, probably two or three inches away from each other. I then looked later on the USGS Geological Survey and found that the Elm Fork Trinity River has holocene-era rocks, so then that rules out Mosasaur I guess? I looked online to see Mosasaur and fish verebrae to see if I could

Indonesian Red Copal (Subsoil to Surface Horizons, Late Holocene)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
This specimen weighs 36.0g and measures 65x40x25mm; several small fragments of plant material are contained within its translucent, reddish mass. Originating from the island of Java, this variety of copal is a fairly recent discovery; it is recovered from various soil levels, near to or on the surface of the rainforest floor. Rough specimens usually exhibit a thick, whitish exterior crust; Indonesian red copal is very soft, reacts readily with acetone, and can be scratched with a fingernail. -

I went to the Zandmotor recently while visiting The Netherlands and wanted some clarity on some of my finds. I found a number of shells, two fish vertebrae, and two different mammalian bone fragments. This, however, is all I can make of any of them, and would appreciate more specific ID's if anyone out there knows. The shells should be middle Pleistocene (if they're not actually recent shells lol), and everything else (likely) late Pleistocene. Thank you! Fish Verts: Perhaps not fossil-- Baltic Macoma? Not sure about this eithe

Greetings, Sorry, if slightly off-topic. Found this tooth-like thing near Vladivostok, Russia, 10-20 meters from sea line, among remains of an early iron age culture (800-300 BC). Any help would be much appreciated!

I found this rock on Ocean Beach in San Francisco. I have In the same area over the past few weeks recovered several fragments of Sand Dollar fossils probably about two million years old, according to a local geology/oceanology professor who recognized them right away. I am wondering if this rock might be a turtle scute as I have seen similar looking samples online that were Holocene turtle scutes. The sand dollars were the first fossils I’ve ever found outside of fossilized clams so I have no problem if this is just a rock. Many thanks in advance for the expert guidance and help.

Can anyone help me with the following fossils? (what species etc.). Made a selection of a bigger compilation (most important fossils are shown). Kind regards

Can anyone help me to determine the fossils on the pictures? They are all found were bone fragments from Pleistocene and/or Holocene material has been found. Could the teeth belong to Bos primigenius (Bojanus, 1827)? I think they belong to the above mentioned art. I also found some horse teeth at some locations. The brownish coloured teeth are from Zeeland. The black teeth are from Limburg (found in water/creeks). They are black and/or brown and fossil (not recent material judging by the colour and erosion).

Hi all I have been looking through some of my cave finds and want your thoughts on two specimens that look much older than the other bones. All these bones where found in one cave that could have possibly been inhabited by humans as recently as 370 years ago, before colonialism. I have found some ostrich egg fragments as well as sea shells in the upper soil layer, this might be an indication of human activity, I have also found evidence that the site was occupied by scavengers and predators like the lynx and leopard at some points. The site is approximately 1.5km from the nearest coast an

This is a cave find I can't place. I think its a partial tibia, but from what family? The identification of this bone could help me with the time-line of the cave. Thanks

Wayward / Wrongway Holocene Southern elephant seal reported from Indiana (Wabash River)
Oxytropidoceras posted a topic in Fossil News
For an extreme example of a wayward marine mammal, look at the below open access paper. Valenzuela-Toro, A.M., Zicos, M.H. and Pyenson, N.D., 2020. Extreme dispersal or human-transport?

I have here a polar bear tooth from St. Lawrence, Alaska. I was told it was fossilized, Pleistocene to be precise. The seller had other similar teeth available on offer, in darker shades, claiming they were all fossilized and simply preserved in different ways. Ultimately, I chose this one. As far as the literature goes, it has been argued that the polar bear does go back to the late Pleistocene: Ingólfsson, Ólafur; Wiig, Øystein (2009).

I know bone fragment ID's are usually left at just that "bone fragments," but I've seen some pretty amazing ID's here lately and this is my favorite little puzzle. It was found on Edisto beach which harbors Pleistocene mammals mixed with Miocene and Holocene aquatic creatures. More info on the location (including a list of mammals) can be found here: https://markgelbart.wordpress.com/2010/05/25/the-edisto-beach-fossil-site/ It's completely hollow and has what appears to be healed over bite marks. Even if it can't be ID'd, if anyone can confirm or deny if the markings are really bit
