From the album: Gastropods of the Tamiami Formation
Order Neogastropoda Family Fasciolariidae Pliculofusus acuta (Emmons, 1858) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: APAC, Sarasota County, Florida USA. Status: Extinct Notes: Most Plicofusus in the Pinecrest have been referred to as P. scalarina, however they appear closer to the Pliocene forms from the Carolinas. P. acuta has fewer, but more prominent ribs than P. scalarina as well as more angulated whorls. -

Order Neogastropoda Family Fasciolariidae Heilprinia caloosaensis (Heilprin, 1886) Stratigraphy: Pinecrest Sand Member of the Tamiami Formation Location: SMR Phase 10, Sarasota County, Florida USA. Status: Extinct Notes: This shell is sometimes noted as Heilprinia carolinensis. Dall (1892) in his description of Fusus caloosaensis carolinensis, stated that further one collects north, the heavier and thicker this species became, but noted that intergrades existed. Both slender and thick forms are found in the Caloosahatchee Formation. In the FLMNH database, specimens in Florida are typically identified as H. caloosaensis while those in the Carolinas are listed as H. carolinensis. -

Sciara willershausensis together with the much smaller and much more common Sciara strausi. Taxonomy according to Kohring & Schlüter 1993. Morphology according to Kohring and Schlüter, 1993, p. 193 (translated from German by oilshale): “The body length is about 7.2 mm. The wing length is between 4.8 and 5.2 mm. The head is very small. The antennae are only incompletely preserved, in total the antennae are on average 1.5 mm long. Individual antennae are indistinctly recognizable in outline. The thorax is 2,1 mm long and oval shaped. The abdomen is 4.5 mm long and evenly pointed. The wing is round curved. Sc and R1 stands out clearly due to dark coloration. Pedicel of m-fork only slightly longer than branches M1 and M2. Cu with very short pedicel, branches distinctly longer..." Line drawing of the forewing from Kohring & Schlüter 1993, p. 192: Identified by oilshale using Kohring & Schlüter 1993. Reference.: Kohring, R & Schlüter, T. (1993): Sciariden (Insecta: Diptera: Nematocera) aus dem Oberpliozän von Willershausen. Berliner geowissenschaftliche Abhandlungen (E), 9, p. 191-199; Berlin

North Carolina Cretaceous or Pliocene Reptile or Cetacean Bones?
fossil_lover_2277 posted a topic in Fossil ID
So, I found these 5 bones, and firstly, I need to know if they are cetacean or not. If not cetacean, then they are likely crocodilian, mosasaur, or I guess possibly turtle. They come from North Carolina, either from marine Cretaceous Black Creek group deposits, or there is a chance they could be marine Pliocene (hence why I would like to either confirm or rule out cetacean if possible). The area they come from is mostly Cretaceous, but I have found a few Pliocene shark teeth there, and stratigraphic maps show nearby Pliocene stratum, so I’m not totally sure (the area is in Cretaceous stratum on the map, but Pliocene is close by). These bones have distinct shapes so I think they may be IDable...but on my own I’m lost. Thank you for any help you can provide!!!!! Bone 1 (pretty sure it’s a rib): Bone 2: Bone 3: Bone 4 (I think this one is a rib too): Bone 5:

Florida Paleontological Society (FPS) Fall 2021 Field Trip
Shellseeker posted a topic in Fossil Hunting Trips
This has been a very busy week for me and my fossil addiction. I was out to the Peace River on Tuesday, attended the Lee County , Florida Fossil Club meeting Thursday, went to the Friday night dinner preceding the FPS meeting and was fortunate to be part of those FPS members who went on a field trip to a Pliocene-Pleistocene Shell Pit in Charlotte County, Florida. I know at least 4 other FPS and TFF members who also participated in this Outstanding Field trip. 1) I have volunteered to write_up this field trip for the next FPS Newsletter. I will do that and when complete, will post a copy to this thread. 2) I will also, as time permits, post photos of my many finds.. They need to be cleaned first. @calhounensis is a FPS member and participated in the Shell Pit hunt. He was extremely generous in giving me a number of horse teeth he found, suggesting that I would enjoy them more because I seem addicted to fossil horse teeth. 3) I will attempt identification of all these horse teeth and post my success or lack thereof. Right now the Horse teeth are soaking in water. In addition to these horse teeth (Equus and pre_equus) I heard that a Mako, and some Great Whites, some echinoids and Sand Dollars were found but the dominant % of finds are seashells and corals.... they were all over the ground. I invite any and all TFF members in attendance to post comments on the trip, photos of a few or many of their finds, or not. I have had a great week, just in the company of my numerous fossil addicted friends... but I am weary, and will get some sleep before my next post to this thread. Jack

This is a 1st for me, a denticle that is this thin, this large. I dimly recall hearing somewhere that these came from sharks, not stingrays. Let's see if some more knowledgeable than I concur. @Al Dente @MarcoSr@siteseer

Well, I found this toebone, pretty clearly a proximal phalanx. and a little searching on TFF turns up these photos from @Harry Pristis.. I see a lot of similarities, but then also some differences..... Wouldn't you know, it is heavily damaged exactly on the proximal ends of the bone, which I see as one of the most diagnostic features. but what else can it be? White-Tailed Deer fossils can be found in the late Pliocene and Pleistocene Deposits of Florida. They become especially abundant in the Late Pleistocene, after the Camels and other sizable Ungulates go extinct. It is the same species of White-Tailed Deer that lives today, Odocoileus virginianus.

This was an interesting day. I do not find many hoof cores, especially with 2 proximal phalanx, one of which seems to "fit" pretty well. The pieces I connected came up in back to back sieves. I wonder a number of things. Is the combined Ungual/Proximal set od toebones, small, average or large when compared to other Equus fossils. Later in the day, another toe bone dropped into my sieve (just before the thunderstorm started). The width of this last phalanx is 19.75 mm. All comments and identifications appreciated. Jack

I usually go hunting 2-3 times a week, and normally I find a couple of fossils that I do not recognize or even when I do recognize a fossil as an ankle bone, I am just not sure what it is.... But sometimes, I identify them anyways. I use one of the numerous outstanding photos provided by @Harry Pristis. Here is one of them, and then using the above chart, a couple of recent finds identified by the above chart.... Harry's continuing contributions of clear and effective pictures are one of the real strengths of TFF. Thanks Harry.

http://www.thefossilforum.com/index.php?/topic/118893-little-hoof-core/ The thread above made me think of a couple of worn bones, found this year in Peace River Fm, that I thought "might" be hoof cores The 1st is 75 mm wide and the 2nd is 50mm wide. @Brandy Cole @Harry Pristis Loved your picture of hoof cores, Harry. Do you think either of these is a hoof core?

Hello all, I made two drawings (and edited both of them) of a O. Megalodon (Otodus Megalodon) shark. The first one is a pencil drawing (black-white) on a original white background (made it coloured, blue). The second one is a Megalodon smelling whales. Enjoy! Perhaps other people can post here their Megalodon drawings/paintings. Kind regards, Ruben

I found this tooth in Greens Mill Run in Greenville, NC. I’m leaning towards croc due to the size of the dental cavity relative to the size of the tooth, but perhaps it is a mosasaur. It has one carina on the anterior side of the tooth, none on the posterior side. Also, if it is croc, is there a way to identify whether it’s Cretaceous or Pliocene? Or if either croc or mosasaur, perhaps genus ID? Thanks!!!
