Fairly confident this is a P. contortus but would love a second opinion. From the Calvert formation.

From the Calvert formation I think it’s a Carcharhinus sp. but would really appreciate a second opinion.

Hey all! Still working on the Cabezon fauna, which looks to be never ending! I have, so far, over 16,000 fossils (mostly selachian teeth) recovered from ant hills. I just went out yesterday and got another 100 pounds of ant hill to go through. Although most of the teeth are scapanorhynchus and cretolamna, there are several other species represented, including some very small orectolobids. I also run across a few that I have not seen in the literature or in other museum collections, so I am going to post a few this week to pick your brains. The first one could be

What did Petrodus sharks look like? (Are they known only from denticles?)
Gramps posted a topic in General Fossil Discussion
All, I have been finding a few dermal denticles in Northeast Oklahoma Pennsylvanian shales. Based on published reports and images from our area, I believe these are Petrodus. I’ve attached an image of two denticles I found yesterday. I’ve been looking for images of the entire shark because I’m curious about the animal’s overall appearance; however, I’m only finding images of the denticles. Do scientists know what these sharks looked like, and if so, does anyone know of resources containing overall images? Best wishes. -
Going through my collection and trying to put a name to these. All from the Calvert formation. Please note the numbers on the paper identify the different teeth.

Hello. I was wondering if I could get some recommendations for a good shark tooth identification field guide for the Carolina's (or just a general guide). I currently use 'Fossil Shark Teeth of the World' by Joe Cocke. I like the book and layout, but the pictures are black and white and often not very good. I would also be interested in a more desk bound book if it included more high quality pictures. Thanks!

Calvert County, MD beaches, Matoaka Lodges, Miocene diversity, September 2020
Chris Carpenter posted a topic in Fossil Hunting Trips
Here is a brief report from one of our latest forays into Calvert County, MD. The well-known stretch of shoreline along the western Chesapeake Bay is loaded with Miocene fossils, with the Calvert, St. Mary's, and Choptank formations progressively exposed along a ~24 mile stretch of beach and cliffs. We found an Airbnb in Lusby, MD which was not too far from Matoaka Lodges, which seemed the best bet since the nearly 2 mile walk to the beaches at Calvert Cliffs State Park is impractical for our family at this time. Covid-19 and Maryland's onerous private land regulations can make it -
Hello! Help please to ID. Max. length: 8 mm. Location: Western Ukraine. Age: probably Miocene. Thanks in advance!

Hi all. I'm pretty sure these are GW teeth. I don't see any evidence of a bourlette. The only think troubling me is the root. I can't remember seeing GW teeth from Aurora or GMR (where these are from) with this type of curved root. Maybe transitional? Thanks for you time.

Figured I might sift through some shark teeth and misc. aquatic creature fossils I have stored in a couple boxes and post them here and perhaps learn a bit more about them from more knowledgeable members. These aren't arranged in any order, unfortunately, as I really don't know much about sharks and am still learning, so if anything stands out, please let me know! I must also apologize for the poor photo quality-I don't have any fancy set ups and this is just a quick perusal of what I have and throw it up here on the forum kinda night, haha. Scale is in mm/cm; I have listed the names and count
