These are various shark teeth from the north sulfur river in ladonia, tx of varying completeness. I'm not sure of the species of the fragments, but the one with most of the root is definitely pseudocorax granti.

Help requested identifying these shark teeth from Calvert Cliffs. After a while, I find some teeth look similar to others. Thanks!

Hi, My kiddos father picked this up at a flea market and was told by seller it was a megalodon tooth. He gave it to our son for Christmas. It doesn't look at all like a megalodon tooth to me. I had to manage my son's expectations when he opened it and let him know that it probably not be a megalodon tooth, but it's still really cool. I promised him I would try and find out what it is. My son is two weeks away from being 6, he has Asperger's and is absolutely obsessed with sharks. It's all he talks about. Would someone please identify this for me?

I had a fun trip looking for shark teeth and artifacts yesterday at the North Sulphur River Texas. I found a large Enchodus tooth, nice shark tooth, mosasaur jaw section, other assorted fossils and some cool artifacts. Weather was perfect.

Here's a couple of quick hunts I forgot to post from the last two weeks. Post Oak Creek and North Sulphur River Texas. I really like the ammonites.

Trying to figure out what this tooth is exactly, still working on my identifying knowledge. First thought was young Meg but not sure

With this post I have now posted on TFF at least one jaw from a species from each of the 9 shark orders (Hexanchiformes, Echinorhiniformes, Squaliformes. Pristiophoriformes, Squatiniformes, Heterodontiformes, Lamniformes, Orectolobiformes, and Carcharhiniformes). To understand and id fossil shark teeth it really helps if you are familiar with extant shark teeth. This post contains pictures of an extant Echinorhinus brucus Bonnaterre, 1788 (Bramble Shark) jaw. Links to my previous TFF posts on extant shark jaws can be found at the below TFF link. My Extant Shark Jaw Collection There are only two species of Echinorhinus, Echinorhinus brucus (Bramble Shark) and Echinorhinus cookie (Prickly Shark). There is some dentition/tooth-design detail given for the genus Echinorhinus in the published literature but no features that might provide a means of distinguishing between the two extant species. The only sure way to id an Echinorhinus jaw to the species is to see the actual shark that the jaw came from. To illustrate the differences in the two species of Echinorhinus I’m providing some illustrations from Compagno 1984 VOL. 4 “SHARKS OF THE WORLD An Annotated and Illustrated Catalogue of Shark Species Known to Date Part 1 - Hexanchiformes to Lamniformes”. Echinorhinus brucus (Bramble Shark): Echinorhinus cookie (Prickly Shark): Note that Compagno calls the Echinorhinus scales dermal denticles because of their large size and features. These scales look much more like the dermal denticles from the mid-line of rays than the much smaller placoid scales from other sharks and from rays. Echinorhinus brucus (Bramble Shark) jaw, 7 inches by 7 inches, (This jaw is definitely an Echinorhinus jaw and I’m using the species id provided by the seller of this jaw who is a very reputable seller of shark jaws) that has been professionally cleaned, prepared & shaped: Echinorhinus jaws are extremely thin, almost paper thin. Here is a random picture of an Echinorhinus jaw from e-bay. This is what an Echinorhinus jaw would look like without being professionally cleaned, prepared & shaped. Below are teeth from the jaw. The teeth display monognathic heterodonty. The teeth are very similar in both the upper and lower jaws and don’t change a lot moving distally in the jaw. Adult teeth can have 1 or 2 mesial and distal cusplets which are absent in young sharks. Weak serrations can be present. The below teeth show evidence of weak serrations. Because a number of the active first row teeth in this jaw are damaged, I’m only taking pictures of the better teeth. Teeth from the right and left side of the upper jaw: UR1 (10 mm): UR2 (10 mm): UL 4 (10mm): UL 8 (8 mm): UL9 (5 mm): Teeth from the right and left side of the lower jaw: LR2 (12 mm): LL 5 (10 mm): LL 7 (10 mm): LL 9 (7 mm): LL 10 (4mm): You can see in the below pictures that there are 4 upper rows of teeth and 4 lower rows of teeth in this jaw. The upper jaw has 9 tooth files left and 10 tooth files right of the symphysis. There aren’t any symphyseal teeth. The lower jaw has 10 tooth files left and 10 tooth files right of the symphysis. There aren’t any symphyseal teeth. Marco Sr.

Interesting story. https://riverheadlocal.com/2018/12/14/local-teacher-finds-likely-fossilized-shark-tooth-on-baiting-hollow-beach/

Today I went for my first "serious" (ahum) shark teeth hunt. Over the last few weeks I was keeping my eyes open while walking the beaches of Sullivans Island and Isle of Palms with my wife, but today it was "game on". Left the house at 8:00AM and drove to Folly Beach as I had been reading that of the beaches closes to me that was the best to look for teeth. Weather was nasty, cold and windy. Tide was still high but outgoing. Hardly anybody on the beach. Spent approximately 3 hours without finding anything. I was mainly looking in the accumulations of shells, seaweed, rocks, pottery higher up the beach. Saw one person picking up things at the waterline and decided to ask her what/how she was doing. We had a friendly conversation. I explained that it was my first time. She showed me a handful of small teeth that she found by looking for them as the shallow waves are rolling ashore. I decided that, as I had nothing to lose, to follow her method/advice and started to look close to the waterline as well. I do not think that more than 5 minutes passed before I found MY FIRST TOOTH EVER !! I know that compared with what others here report it is not much, but for me it meant that I had succeeded in my quest. Shortly after, I found a second one, but at that point the nasty conditions were taking their toll and I decided to call it a day. I will be back.

I found this in the gravel bed of a creek today in Grayson County, TX. Is it a shark vertebrae, or possibly mosasaur? Thanks for any help.

Just a simple question by a newbie ..... Just started this new hobby and found my first couple of teeth. Need some directions about how to identify. Books, websites, forum threads etc. Just a little push in the right direction and I'll get moving ....

I have this tiny shark tooth in my collection from America, but it kinda looks like a tiny, worn meg?

Hello! I've been hunting for about 16 years now in the Calvert Cliffs beds. Have found quite a few nice specimens. Hope to see some great fossils here! Just a pic of some of my best things....
