Dug this small fossil out of a sandstone boulder that was littered with bivalves and gastropod. A lot of the fossils found in the sandstone date back to the Pliocene so I can only assume it is from that period also. Thanks

A surprise find of a new species for me. IT was in a clump of matrix on one of the specimens I brought home. I.D. was obtained from "Pliocene Molluscs From The Yorktown and Chowan River Formation in Virginia" Lyle D. Campbell 1993

Recently I’ve found some strange fossils from an area in Simi Valley (Southern California). I had thought there were only shells, but turns out there is vertebrate material! Among other fragments, I found a couple big whale vertebrae as well as this piece here that I am unsure about. I’ve seen some mentions of fossils from smaller marine mammals like dolphins and pinnipeds, maybe it’s one of those? Unfortunately there only one end present, so I’m not expecting to get anything too specific. The formation is about 5 million to 11 thousand years more. Hopefully I can get some more interesting things from that spot. Thanks!

I found this bivalve in a clump of matrix that was attached to one of my other finds on a recent trip to the Tar River with @MikeR and @AshHendrick. I have never found one of these before nor seen one. Pliocene Yorktown Formation Rushmere Member. My best guess on this one is Pododesmus sp. It is 1.53 inch long (39 mm) and 1.42 inch wide (36.3 mm)

G'day everyone! I reccently returned from a fossil trip to Portland, VIC searching for pliocene shark teeth and bones. Dad and I came back with some nice stuff but I also found this bone that has had me stumpted. Most bones collected from the site are fragmentary but this one appears to be whole but I have no idea what it is from. The bone is 30mm long, around 5 -6mm wide and very thin (Around 1mm probably a bit less) The fossil is pliocene in age, fossils found from the site include: Shark, fish and ray teeth, cetacean teeth and bones, terrestial mammal teeth and bones and rare avian material. Any help would be much appreciated. Thanks, Dan

The grey tooth on the right is a small posterior megalodon tooth found in the peace river Florida. The copper tooth was found in a very shallow creek part of big brook NJ. Is it possible that a meg could have swam farther north like modern great whites do during a split time when the water level overlapped the big brook area and dropped it? I’m still new at identifying teeth but they seem VERY very similar

Recently I aquired this Carcharodon tooth from Sacaco, Peru whose serrate conditions seems a bit peculiar to me. I can't really decide whether or not this tooth is from a late-stage hubbelli or an early carcharias. The serrations seem to wear/taper off just short of the tip on one side and abruptly end near it on another, and some (although not all) of the serrations appears to be angled in a way, although I suspect some may be due to wear. My thoughts on the serrations keep seesawing in my head. Would this tooth better represent a late-stage hubbelli or a carcharias? Thanks for any and all answers. Lingual

Took a quick 1 1/2 hour trip yesterday afternoon to a Pliocene deposit on a river here in eastern North Carolina. I believe it is Duplin Formation. Was the first one there when the water got low enough, found some nice stuff. The Pliocene there sits on top of Eocene Castle Hayne limestone, so I got a few echinoids as a bonus. Two 2 inch plus hastalis, a 1 1/2 inch great white. A 1 3/4 inch croc tooth. A nice vert some big tigers, a broken whale tooth and Cacharhinus sp. Also a nice ray tooth file. Possibly Aetobatus. The two echinoids are Eurhodia holmesi.

G'day Everyone! I would like some help identifying these shark teeth I found in Portland, VIC around 5 months ago. These fossils are Pliocene in age and come from the Portland Limestone I believe. They have been sitting in my collection for a while and I have become increasingly interested in them. I have done some research and believe they are some kind of Hemigaleidae shark teeth. I would like to confirm this because there is very few Hemigaleidae fossils recorded in Australia. Thought I would get the community opinion. Thanks, Dan

These are rarely found at this locality, especially with both valves.

One of the more spectacular and uncommon bivalves from the Yorktown. Only the third example I have seen from this site. Reference : Pliocene Molluscs From The Yorktown and Chowan River Formations in Virginia Lyle D Campbell 1993

hi all, Here are three teeth from the Pliocene Yorktown at LC. When found, I was told "pilot whale", which hasn't helped much. I do believe that they are from a tooth cetacean though. Could anyone hazard a guess as to genus/species? thanks in advance

Good evening, i found a bone that I believe to be a toe bone of a mastodon or mammoth. The bone was found in the Neuse River in Craven County, NC. Thank you in advance for assistance in identifying this piece.

Order Neogastropoda Family Muricidae Vokesimurex rubidus (F.C. Baker, 1897) Statigraphy: Golden Gate Member of the Tamiami Formation Location: Boca Grande Aggregates, Lee County, Florida USA. Status: Extant Notes: Its common name is the Rose Murex. -

Order Neogastropoda Family Muricidae Calotrophon ostearum conradi (Mansfield, 1930) Statigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: The spire is higher and body whorl sculpture stronger than extant C. ostrearum. Possible intergrades exist between C. ostrearum and C. ostrearum conradi would exclude C. conradi to be considered a separate species, however it is a form that does not exist in recent populations. -

From the Meherrin River in NE North Csrolina. Local geology and preservation suffuse Plio-Pleistocene. I've eliminated tuna, grouper, wahoo, seabass, drum, sturgeon and tarpon. Im out of ideas. Thoughts?

Good morning, second post today! I found this bone in the Neuse River in Craven County/ Eastern NC. The shape of the bone is throwing me off on my google search. Can anyone identify the bone? Apps size is 3.5 inches by 3 inches. Thank you
