The genus Alopias, commonly known as the Thresher Shark, has been around for millions of years. These sharks use their abnormally long, whip-like caudal fin to stun their prey. This fin can grow to become more than half the length of shark's entire body. It is a strange and fascinating creature, and has been one of my favorite sharks ever since I was a little boy. Today, we fossil hunters can find the fossilized teeth of Thresher Sharks. They are typically rather small, and relatively uncommon. They look really cool in my opinion, and they're among my favorite types of shark teeth that are on the smaller side. So for this thread, SHOW US YOUR THRESHERS! I'll start by posting a neat little ring I made with my best Threshers so far. I'm excited to see what you all have found. Like I said, most of these teeth are pretty small, but I do understand that there's a species of Giant Thresher that can apparently be found at Calvert Cliffs and elsewhere. I've seen a few pictures, but never found one. Let's see what you all got!

Isolated theropod Teeth from the Kem Kem Basin continue to be a mystery. Plan on documenting all the different morphologies I have in my collection to see the variation that exists. Currently we cannot identify any one to a specific species or genus possibly family. I can provide discussion and aid in identification at some point. Just a note, different morphologies do not necessarily mean different species. There are lots of tooth variations in the dentition of a theropod, why its so difficult to nail down an ID even in the best of circumstances. Morph Type 1 Anterior Tooth (possibly Carcharodontosaurid) Distal margin is almost straight Mesial margin strongly recurved Mesial carina extends 3/4 crown height Denticles are oriented towards the tip Serration Density: Distal - 2/mm (More dense toward the base) Mesial - 1.7/mm (More dense toward the base) Morph Type 2 (possible Carcharodontosaurid) Anterior Tooth Distal margin is slightly concave Mesial margin strongly recurved Mesial Carina extends to the cervex Denticles are oriented toward the tip Interdental sulci present Serration Density: Distal: 2/mm (More dense toward the base) Mesial: 1.9/mm (More dense toward the base) Morph Type 3 (possibly Carcharodontosaurid) Dentary? Mesial Mesial carina extends 3/4 crown height Denticles parallel to the base and rounded at tip Serration Density: Distal: 2.2/mm (More dense toward the base) Mesial: 2.4/mm (More dense toward the base) Additional Example Morph Type 4 (Possible Dromaeosaurid like) Lateral Tooth Tooth is recurved Mesial Carina extends to 3/4 crown height with a lingual twist Denticles parallel to the base Serration Density: Distal: 3.6/mm Mesial: 4.6/mm Additional Example Serration Density: Distal 3/mm, Mesial 5/mm Morph Type 4A (Dromaeosaurid like) Tooth is slightly recurved Mesial Carina extends to base with a lingual twist Denticles parallel to the base Serration Density: Distal: 3.6/mm Mesial: No Serrations Additonal Example Serration Density: Distal 3.3/mm, Mesial: No Serrations

A good friend of mine is working in an area real close to Cape Town, South Africa. He's an avid fossil collector and wants to know if it's legal to collect fossils off any of the beaches there. I did some research and it appears that South Africa has some pretty strict laws/rules that prohibit the collecting of any fossils, removing them, exporting them, etc. without a permit from South African Heritage Resources Agency (SAHRA) . Permits seem to be issued only when specimens go to a museum or university for study, etc. Just curious to know if this is still the current law/situation so my friend knows what he can or can't do/collect etc.

Ukrainian fossils for Vertebrate teeth and bones
Anomotodon posted a topic in Member-to-Member Fossil Trades
Hi everyone! I am really interested in collecting vertebrate fossils. I have a lot of things to offer: - vertebrate fossils from Eocene of Kyiv, Ukraine and Albian-Cenomanian of Ukraine and Russia (various species of shark teeth, bony fish teeth, turtle shell fragments) - Pleistocene mammal, fish and turtle bones from Kyiv, Ukraine (unfortunately, I am not very good at identifying mammal species, but I have a large selection; mostly rodents or other small mammals, I have larger bones, but they are less complete) - crabs from Kyiv Eocene (Eocarpilius (?), up to 4 cm, not perfect, but with almost completely preserved caparaces and some appendages) - Silurian invertebrates from Podolia, Ukraine (mostly corals and small brachiopods) - also some small Devonian placoderms from Podolia, Ukraine (Kujdanowiaspis) - various Ukrainian and Russian ammonites and orthocerid or endocerid nautiloids - a lot of Miocene and Pliocene molluscs from Ukraine - some Carboniferous plants from eastern Ukraine - some random things, ask me if you are interested in something else In return, I am mostly interested in Paleozoic to Cretaceous shark and reptile fossils (both bones and teeth), especially in specimens from rare locations (especially Australia, don't have any vertebrates from there, and any Permian/Triassic vertebrates or dinosaurs/pterosaurs/marine reptiles from other periods). PM me if you are interested, please. I will send you the pictures of specimens you are most interested in. I also accept sales instead of trades. Here is an example of some Eocene fossils from Kyiv I have for trade (here are various sandsharks, Isurolamna, goblin Anomotodon, turtles, Carcharocles, Notorynchus, makos, Jaeckelotodus, Striatolamia, rays, chimaeras, bony fish, Physogaleus). I have much more specimens available, this is just an example.

I've not had a chance to post my finds here in a while but over the past few months I've found some new specimens of Lower Carboniferous/Mississippian marine shark teeth I wanted to share! These were collected at various sites in the Midland Valley of Scotland from the Blackhall Limestone, an extensive formation with interesting variations in fauna at each different locality. Ctenoptychius sp. Anterior tooth in lingual view, 6mmx7mm.

Hello Everyone! It's been a minute since I've had the pleasure of finding any fossils worth posting here, but I was lucky enough today to squeeze in a couple hours of hunting. I noticed several sets of footprints around my usual hunting site - others had picked through the material recently. Undeterred, I made my way along the river visually scouring every square inch of exposed grey-brown Oligocene formation and gravel. Im glad I stuck with it because I was rewarded with several nice (albeit small) teeth from the extinct mega-tooth white shark, Carcharocles angustidens as well as a slew of smaller teeth. Then, just as I was ready to start hiking back to the car, I noticed the root of a VERY large mako tooth sticking out of the ground. When I pulled it up I was reminded of the sword in the stone..it just kept going and going. At a little over 2.8" it's one of the largest Isurus desori teeth I've ever personally seen. It's in great condition with exceptional color to boot. Thanks for taking a look and as always... Happy hunting! SOSC

A - lateral; B, C, D - anteriors. Anterior teeth have typical of Heterodontus V-shaped root and marked cutting edge. Unlike H. canaliculatus anteriors, anteriors of ‘H.’ upnikensis have more convex labial side (so that cutting edge is situated in the middle of the lateral surface) and no lateral cusplets. Crown generally widens near the base, so most teeth have regular triangle shape of a labial face. Teeth located closer to symphysis display more mesiodistally compressed crowns. Enamel is smooth on both faces. Lateral teeth are also different from H. canaliculatus: they have lower and shorter central occlusal ridge and lateral ridges are highly anostomosed on both sides, so that complete tooth ornamentation has a net-like appearance. ‘Heterodontus’ upnikensis is an enigmatic species. No associated tooth set has been found yet, consequently it is impossible to tell that a given set of laterals actually belong to ‘H.’ upnikensis. There is a possibility that lateral teeth described here as ‘H.’ upnikensis here belong to another Heterodontus species not represented by anteriors in Kanev collection. They were assigned to this species because there is generally some degree of tooth plan similarity between anteriors and laterals of the same species. Laterals described here have: 1) relatively weak and short central occlusal ridge; this trait is similar to ‘H.’ upnikensis shorter cutting edge because of lateral cusplet absence; 2) more bilateraly symmetrical crown shape and ornamentation across the central occlusal ridge than in H. canaliculatus; this feature is analogous to relatively equal thickness of labial and lingual face on ‘H.’ upnikensis anterior teeth. Also, anteriors of ‘H.’ upnikensis are a lot more common in studied locations than H. canaliculatus, and the same trend applies to two found Heterodontus lateral teeth morphotypes with H. canaliculatus teeth being a lot scarcer.
