Time for the Bullheads ! Show us your Heterodontus fossils
fossilsonwheels posted a topic in Member Collections
The next shark on the list to start a thread for are the Bullhead Sharks. The order is represented by a lone extant genus, Heterodontus, and a few extinct genera. Heterodontus is a cute little shark. One of my personal favorites partially because they look like they should not be a rugged survivor but they really are. They have been around since the early Jurassic and basically have not had to change much to survive. They are not the torpedo shaped super shark for sure. They are small, sluggish bottom feeders but they are incredibly well adapted to their environment. They have very powerful ja -
Cenomanian Shark teeth from Russia for Heterodontus teeth
fossilsonwheels posted a topic in Member Fossil Trades Bulletin Board
From the Saratov Region of Russia, we have Cenomanian shark teeth from the Melovatka Formation We got quite a few teeth from this formation and I have filled the displays, finished a couple of trades with a few of these and I still have many many teeth for give aways. Most of the teeth were Striatolamia with quite a few Archaeolamna. We found a few other interesting teeth and many are really Lamniformes indet so some of the ID's are educated guesses. Still these are some interesting teeth from a cool formation. They are all small teeth, under .5" 10 Eostriatolamia ( th -
We have our Secret Santa package all ready to go and just got done organizing our loose shark teeth. I found a bunch of STH material that I had set aside for a trade that never materialized. I totally forgot I had them so here they are. This is a package deal, I don’t want to split them up. Saves on shipping. This would make a cool Christmas gift for somebody and we aren’t asking much in return.

Many forum members are familiar with Cookiecutter Creek in South Florida. This is a small creek that well-known forum member Jeff @jcbshark was kind enough to share with me a little over 3 years ago. Jeff had posted photos of the tiny Cookiecutter Shark (Isistius triangulus) teeth that he had found picking through micro-matrix from this creek and that started my quest to obtain a tooth from this very unusual little shark. After picking through many gallons of micro-matrix from the Peace River and some of its feeder creeks without once laying eyes upon a single Isistius tooth (but finding tons

Giving my Heterodontus sp. tooth to a museum.
David in Japan posted a topic in Partners in Paleontology - Member Contributions to Science
Hi guys, few weeks ago I created the following topics to help me identify a tooth I found here in Japan. I am sorry, I won't be able to give you accurate information until I get green light but I will update this topics as soon as I can say more. I get some help for everyone and @Anomotodon who pushed me in the right direction with his suggestion. After further searches, I contacted a Japanese professor who confirmed me it was an Heterodontus indet. tooth. I am particularly excited because it could be (according to paleodb.org) the oldest Heterodontus tooth found in Ja- 11 replies

Found in micro matrix collected at Ernst Quarries.

I'd like to get some opinions on my tentative id of this specimen as a dorsal spine from the Bullhead/Horn shark (Heterodontus sp.). I haven't been able to locate many good images of these spines and this specimen is significantly larger than the few photos I've found. Is this a dorsal spine and if so what is the normal size range? This was collected this past weekend at Ernst Quarries, Slow Curve (Sharktooth Hill), Round Mountain Formation, Middle Miocene. Any help on the id is appreciated. Also curious if the Heterodontus from that period were larger than the extant Pacific species which d

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 a

From the album: Albian vertebrates of Ukraine
A - lateral of H. upnikensis B, C, D - anteriors. They are characterized by absence of cusplets, compared to contemporary H. canaliculatus. -
This tooth was self collected at a personal site close to home. This site produces exceptional micro material. H. elongatus are very uncommon teeth in the Eocene of N.C.

This crown of a Heterodontus tooth is a rare shark tooth from the quarry Moldenberg near Heidenheim.

Could this be a Heterodontus species anterior tooth? ~6 mm x ~4mm. From Midlothian, TX pit trip.
