I picked up the shark tooth below a while back, labeled as Cretalamna borealis. I'm not very familiar with the species--does this ID appear to be correct? The label that came with the tooth says it was found near Stary Oskol, Belgograd Oblast, Russia, and that it's Upper Albian in age from the Kursk Osteolite member of the Seversk Sandstone formation. The tooth measures 38.6 mm along the slant. One of the root corners is missing and there's some hard matrix still cemented to the tooth near the root margin of the lingual side. @ThePhysicist, I think this one might be a D

Hello! I have found what I believe to be shark tooth (I am unsure if it is) nearby a river in south central Indiana and need help identifying it. This is the first fossil I have ever found so I am pretty new to this. The photos are of the same tooth from different angles.

My wife and I made our way down to North Carolina for the Aurora Fossil Museum's Fossil Festival last weekend. Overall it was a pretty productive trip and we came away with well over 1000 shark teeth, some nice shells, lots of ray teeth, some shark, fish and cetacean verts, small cetacean teeth and a bucket of coral pieces. We heard many of the regulars say that the tailings weren't as productive as other years, but I saw quite a few nice specimens being collected. A few of the larger teeth, most of ours were damaged, but some of the colors are great: Lots of s

I recently got started sculpting digitally, and with this new hammer I am now excitedly looking for nails! My thoughts turned to some of my microfossils, specifically some of my really old shark teeth. Microfossils in general are difficult to appreciate without a microscope, so I figured it would be fun to sculpt a few. My first subject is a Devonian Phoebodont shark tooth that I thought looked neat enough. Besides being some of the oldest teeth I know of (380-390 Ma), they look very different from the teeth of modern sharks (except for those of the frilled shark).

Hello everyone, I found these shark and ray teeth on the seashore between Knokke and Het Zwin, in Belgium. Could someone help me to identify them? Thank you in advance.

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.- 7 replies

I found these back in January but apparently never posted them here (can't find any thread), I'm post mostly to my FB nowadays. I found these in about 30 minutes. They are typically assigned as "Petrodus" but who really knows. Years ago at this site I found teeth from at least 3 shark species including "Edestus". These are from the "Mingus Formation" I believe.

Just a handful of Cretaceous species, most from North Texas. The sea that bisected North America ~85 million years ago played host to a diverse and burgeoning ecosystem that supported many species of sharks. It was likely due to specialization that allowed these sharks to all live in the same place and time. -

My son and I realized that we hadn’t been fossil hunting nearly as much as last year. Last year we found a quite a few interesting finds in the creeks of central Texas. We decided to jump back into hunting this week with a few expeditions. I hear there's a few super-hunters lurking Austin so Jack and I decided to see if the early bird can get the worm. We headed to a new spot around Austin, Texas at 4pm with a temperature of 104 (40 degrees). (Fortunately I was able to fool my son into carrying the heavy backpack.) I like this spot because it’s cretaceous and I’m always hopeful of

Bought this tooth from a shop in Colorado, seller said it was found in the atlas region of Morocco. She said it was a ancestor of the modern Sand shark but was wondering if anyone could give me some more information. Thanks!

I'm pretty sure these are S. raphiodon teeth. They are much smaller than S. texanus with a narrow main cusp and finer striations than S. texanus. Compare: http://oceansofkansas.com/sharks/Kansas/shscap3.jpg -

I'm fairly certain this is a posterior Cretodus - a shark known for producing Texas-sized teeth! At just 1 mm tall, this may be the smallest Cretodus tooth possible. -

The famous "ginsu shark" is a rarer species that can be found here. This is a lateral position; a tooth farther back in the mouth. I've only found a handful and none are complete. -

Symphyseal teeth are found in the midline of the shark's jaw. They are usually small and squashed-looking. Since only a few rows produce these teeth, they are much rarer than other positions. -

The fossils in the creek can have varying levels of preservation: from the pristine glassy enamel seen at the top, to more river-worn seen below. -

These oysters are common in the creek, and support the Turonian age of the fossils. -

I was in my local rock shop today just killing some time before an appointment and I found this tooth in with his morroccan mosasaur teeth. It’s got really fine serrations on the edges so at first I thought shark but that doesn’t seem right either. The folds? Waves? In the tooth is throwing me. Any suggestions? Thank you for looking!

Hello! I have yet again grouped up some more fossils that I found in Post Oak Creek that I found interesting and would like to be ID'd. Thank you for the help! (1) very nice tooth (2) shark or other fish? (3) one if my biggest teeth (4) I think this is a Fossil? I was thinking enamel or ray but I'm not sure (5) I'm pretty sure this is a Fossil, but I could not get any good pictures of it up close unfortunately (I could try to get better ones later)
