On a recent fossil outing, I visited a large shell bed in a creek near Williamsburg, VA that I read to be of the Late Miocene Cobham Bay Member, Eastover Formation. Many of the fossils we found seemed to confirm that this site is Miocene age. We found Chesapecten middlesexensis, Isognomon sp., Glycymeris sp., Ostrea compressirostra, Lirophora sp. However, we also found these three Turritella shell fragments. They measure about 2-3cm in length. I thought these shells looked very similar to the Turritella alticostata posted by @sixgill pete from the Yorktown Fm of NC or the Turritella alumensis posted by @MikeR from the Jackson Bluff Formation of FL. The issue though is that both of these species are from the Pliocene. Turritella plebia is supposedly the species found in the Miocene Eastover Formation, but these shells don't look to be T. plebia. I would normally say that these are probably loose finds from the Yorktown Formation that got mixed in with the other Eastover Formation fossils, but these fossils were found in situ and in layers below those that I found the Isognomon sp. shells. If these were Pliocene aged, I would normally expect that they would be located above the Miocene Isognomon shells. I was wondering if someone might be able to solve my confusion. Perhaps these shells are of a third Turritella species that I am not aware of or perhaps the species I referenced above were not limited to the Pliocene. Alternatively this site could not be of the Miocene Eastover Formation and I am just very confused. Any help is greatly appreciated. Thank you!

Bone fragment found on the York River in Virginia. It is the Yorktown Formation, Pliocene epoch. I'm wondering if it is a vertebrae fragment, and what species it might belong to. It's convex on one side, and concave on the other.

This is a coral fossil found in Myloi Gorge, in Rethymno area. I can't identify it, but i know its epoch is Pliocene because in that area were found fish fossils in matrix dated from the Zanclean subepoch( subepoch in Pliocene). Please, can you try to identify it. Thanks.

As a graduate of the University of Virginia, I thought it would be cool to add to my collection a fossil named after the founder of the university, Thomas Jefferson. I was disappointed to read that one of the best places to find Chesapecten jeffersonius shells - Chippokes Plantation State Park - no longer allows you to collect the shells there. I had also read that Chesapecten sp. shells can be found at York River State Park, but that Chesapecten jeffersonius unfortunately cannot be found there. Is that true? Are there other sites in Virginia where you can find Chesapecten jeffersonius? With the personal connection to UVA and Thomas Jefferson, I would greatly appreciate any help. Thank you so much!

Found this odd 9" long jaw-like fossilized bone in a small creek within the Yorktown formation in Virginia between the York River and I-64. It is atypical of the Baleen Whale and Ice Age mammal bones I have found in the same area. Any help with identifying this specimen would be appreciated.

Chances to get out hunting have disappeared. A lot of rain with Hurricane Theta and then some tropical storms. There is a lot of activity late in the season which means higher faster water in rivers and creeks. So I look back on recent curiosities. Hunting 10 days ago, I pick up a curious rock that seemed to have texture, broken at one end. It was white inside. At a distance of 10 feet and 2 hours digging, I found the smaller end. That might be a shovel mark, and for a second I thought I might have broken it, but 10 feet apart, no way. I really do not like breaking fossils. . Now it looks like a water worn whale bulla with a rock boring mollusk hole at one end. But what about that white inside? What is it? How did it form? A couple of more photos... So, we might say that the white was sand (silica) that filled the bulla, and underwent a "transformation". Note that in the last photo , the white seems to merge with the fossilized bone... Curiouser and curiouser... I certainly look for insight from those who have seen this previously.

Fossil from New Zealand Rewrites Evolutionary History
Dave (POM) Allen posted a topic in General Fossil Discussion
heres a link to a newly described fossil seal that we have been finding bones and skulls of here in taranaki, new zealand for the last 15 or so years. https://www.google.com/search?client=opera&hs=0U9&biw=1496&bih=754&tbm=nws&sxsrf=ALeKk01vc72KwYUUtagYwhLgRk96jWpnXQ%3A1605241533476&ei=vQquX5veHM7w9QPNhoLgBQ&q=new+zealand+fossil+seal&oq=new+zealand+fossil+seal&gs_l=psy-ab.3...33364.36178.0.37013.5.5.0.0.0.0.554.1364.0j1j3j5-1.5.0....0...1c.1.64.psy-ab..0.0.0....0.uRROVU4bIrg- 1 reply

Hi. I was at Ramsholt Cliffs in Suffolk, Uk today and found this strange looking tooth. It’s a very large incisor and looks too big to be from a modern human. Could it be an ape of some sort? The rock formations are London Clay, red crag and coralline crag, on the river shoreline a few miles inland from the Suffolk coast. It is a well known treasure trove for fossils. I also found various sharks teeth, also exciting but this tooth is very interesting! Any help or ideas as to what it is from would be great.

Hi all, Someone offered me to sell his what he called to be a baby mammoth tooth. I have been looking around but I am a bit suspicious about the root. I would appreciate if you would kindly put some expertise on it before I buy it. Unfortunately the origin is not known, but it is probably found by fisherman in the North Sea. Thanks for helping me out! Ronny

Order Neogastropoda Family Buccinidae Sinistrofulgur contrarium (Conrad, 1840) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 8 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Differences in the spire and sculpture of the fossil species separates it from recent Sinistrofulgur sinistrum. -

Order Neogastropoda Family Buccinidae Busycoarctum tropicalis (Petuch, 1994) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Sub adults of this species have been identified as Busycoarctum rapum while adults resemble Busycoarctum maximum. Heilprin (1886) in his description of B. rapum stated that it is a smooth shell lacking shoulder spines. B. tropicalis is more heavily striated with shoulder spines suggesting a different species. -

Order Neogastropoda Family Buccinidae Busycotypus bicoronatum (Tripp, 1988) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: Quality Aggregates Quarry, Sarasota County, Florida USA. Status: Extinct Notes: Although similar in appearance to B spiratum, B bicoronatum is closer to the recent Channeled Whelk, Busycotypus canaliculatus but less inflated. -

Order Neogastropoda Family Buccinidae Busycotypus spiratus (Lamarck, 1816) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA.

Order Neogastropoda Family Buccinidae Laeviscyon planulatum (Dall, 1890) Stratigraphy: Bed 4 Tamiami Formation Location: SMR Phase 10 Pit, Sarasota County, Florida USA. Status: Extinct Notes: Almost identical to L. laevis but lacking a subsutural sulcus. Since both L. planulatum and L laevis are found in the same unit, the sulculus could be variation thus making L. laevis a synonym to L. planulatum. -
