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 either (whelk?), lovely shell either way: Mammal Chunk 1: Mammal Chunk 2: Mammal Chunk 1 again: More Shells (Oysters, a gastropod, and a cockle (I think)):

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).

Horse remains reveal new insights into how Native peoples raised horses

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

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 and around 200m above sea level (could be higher) cave fossils, including hominid fossils dated at 35,000 years old have been found in the surrounding mountains. (made an edit on age from 80,000 changed to 35,000, this could change again as I was just reading some conflicting reports on the area, varies from middle to late pleistocene with some early to middle holocene in the mix) These jaw bones where found in a compact layer at around 300mm below the looser 100mm of topsoil. Jaw specimen 1 is probably a juvenile Papio ursinus (chacma baboon) jaw 2 is from a Cape fur seal, they feel much denser than the bones from the top soil layer, but are not permineralized (like stone) I would like some thoughts on the idea of these being pleistocene material?

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). "Late Pleistocene fossil find in Svalbard: the oldest remains of a polar bear (Ursus maritimus Phipps, 1744) ever discovered". Polar Research. 28 (3). doi:10.3402/polar.v28i3.6131 I know coloration is not the ideal determination of fossilization, and yet I also read that the burn test wouldn't work on a tooth. Is there, then, any way to confirm if this is fossilized?

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 bite marks I'd be over the moon. Furthermore, the bottom is concave. I have a photo of the bottom too if you need it, but I ran out of room for this post

All, Pleasure to meet everyone here. I have been a avid collector of Ohio ancient culture artifacts and fossils for over 30+ years focused on North America primarily focused on Ohio regions. I enjoy walking creeks and hunting fields in my spare time. I recently was walking a creek in my county and came across a strange fossil which appears to be a large tooth or bone. It is not a Mastodon or Mammoth. I would love to post and share with everyone to review. Respectfully, Michael

I know this is quite a long shot but the pores/foramen are just KILLING ME, the shape is so familiar, but I just CANNOT drag it out of my brain. Location: Southern California, Mojave Desert. Quaternary alluvium/older alluvium (depth 8 ft) in an area where mammoths and camelids have been found (3 miles northwest, 5 feet below surface). Pleistocene dry lakes lie just to the east. The bones are at least somewhat mineralized, but obviously have a pretty high level of preservation. Pictured are two separate bones with very distinct shapes/pores/etc. No bones have anything particularly diagnostic nor any obvious processes etc.

Hello, everyone, I’m newly retired after 39 years of teaching. Over the years, I have collected, by purchase, to use as demonstration pieces in the classroom a wide collection ranging from Archean microbial mat cross-sections through time to Holocene cave bear vertebrae. My collection is very diverse through time, if limited in depth. I have a nice collection of Silurian-Devonian trilobites, some nice Devonian-Permian plant material, and a range of Holocene mammal bones; vertebrae and mandibles. ... I taught a variety of upper level secondary courses over the years. As Science Dept. Chair in an independent school, I oversaw curriculum (shorthand for “I got to teach what I loved) For many years I taught an Natural History course to seniors looking at the evolution of the Universe. First term Cosmology-Planetary Science; Second term Evolution of Life. A dream job. Now, I’m trying to complete a more formal indexing of my collection (which includes MANY casts as well). Nice to find you folks. Probably will be an infrequent visitor. Glenn

Ahoi dear forum members. While reading a little bit about rudists some of the structures in picture of a broken Hippurites and the shape of Lapeirusia crateriformis reminded me remotely of a still unidentified beachfind from my last big holiday. That doesn´t say much, as apparently rudist could look like anything they wanted, but still I wonder what the fragment I found may be. Found it in the pacific driftline, broken like you see it. There are some barnacles, some serpulids, maybe a little bivalve also, but I wonder what the enclosing structure is. Any ideas? Aloha, J
