hello friends! I like many folks am fascinated by marine mammal fossils and I have learned a lot for the experience of the members of this forum. I wanted to get some opinions from the forum, both in terms of possible species Identification and potential explanation of condition. I found these 6 whale teeth in a very small patch of gravel, sifting in a river in southern Virginia. Other fossils where found in the same area, there is exposed formation on the river bottom, not sure quite what formation. most fossils seem to be Miocene and Pliocene although some older teeth appear with frequency, though they are mostly heavily worked by the river, or from a heavily reworked layer. I found 5 these teeth on the same day, the sixth on the following trip to this spot. No identifiable “jaw-bone” material was found. The wear and preservation as well as proximity suggest to me these teeth are from the same animal, what do you think? I haven’t seen an example of whale teeth with this level of wear, I’ve got lots of prized bits an pieces that have deteriorated I presume after the animal died. Does this wear pattern seem consistent with an old animal? The longest tooth is a little over 150mm. the roots of the teeth seem distinctive, unlike other sperm whale teeth I’ve seen. Is this an anomalous feature that may aid in identification of a species? thank you all for your time!

Hi! I am an new member. I have been collection for awhile and just started on buying more valuable pieces. A friend adviced me to check this Pachy toe on the forum. The main question is: is it an composit or - as the seller told me - associated? Background information: - Found in Garfield County (near the city of Jordan), Montana by the landowner. - The bones were found in the same hillside (spilling down a little wash). No other Pachy material was found nearby In one picture I the small toe bone is removed (maybe this is the mix-up). Hope you can help! Thanks in advance! Best Regards, Mike Jolink (mikejk_fossils on Instagram)

Just a question about articulated/associated bones
The Amateur Paleontologist posted a topic in Questions & Answers
Hey I just had a question regarding what counts as articulated and associated bones. Let's say I find the partial mandible of some crocodile. The left and right dentaries are connected as they would have been during the animal's lifetime. Would that mean that the bones are associated and articulated? Or would left and right dentaries be considered as one single bone? Sorry if this is a silly question...- 8 replies

I found these two cow sharks (notorhyncus primigenus, bluntnose seven Gill) yesterday, miocene, Brownies beach. They were on both on a previous tide line within four feet of each other. The colors and size a very similar, so is it possible or likely that the lower and the symphyseal are associated? As in, from the same animal?
