Picked this up yesterday. It is easy to get excited on a small package. Looks like G. aduncus symphyseal but is much wider than the ones I see on a google search.

Good morning everyone, I think a couple of people of this forum already posted some of their finds from the Arabian peninsula (Saudi Arabia/Qatar) here but here are some shark teeth that I’m struggling to ID. mom thinking that those might be some kind of Brachycarcharias? Thank you guys for your help!

The New Rarest Shark Tooth in My Collection: Lower Glen Rose
Mikrogeophagus posted a topic in Fossil Hunting Trips
Today I took a spur of the moment trip up to the Canyon Lake area for some hunting in the lower Glen Rose. My first venture into the region took place last year and was only a limited success in that I scored a measly two micro echinoids. The plan for today was to try some new spots in hopes of striking the perfect layer of echinoid diversity. The first site was a complete bust, but the second immediately showed promise when I noticed the ground was littered with broken bits of thin echinoid test. Because I had arrived so close after the recent rains, the ground was still a sticky slop of Glen Rose mud. The combination of running along the slopes and frequent crouching set my calves on fire, but the scent of urchins kept me on the chase. Very quickly I was lucky to encounter some really nice crab claws from Pagurus banderensis. A couple had both pincers still preserved. Surprisingly common was also the tiny crushing dentition of Pycnodont fish. They aren't all that interesting to look at, but the simple fact that vertebrate material was present gave me daydreams of finding an elusive Glen Rose shark tooth. I tried to shake away such a hopeless goal, but it continued to sit in my mind. After a couple hours, I found an Amiid fish tooth and some star-shaped Isocrinus annulatus columns. For whatever reason, I could not find a single echinoid spine, let alone a complete test. I was searching the ground very closely, so my thinking was it may be more to do with the site than myself. As I was doing the usual close inspection, I snuck up on a black figure nestled securely in a pile of Glen Rose matrix. It took a moment to register that I wasn't looking at just another chunk of black bug. I safely stashed the two pieces of Polyacrodus. Sadly, the third fragment was nowhere to be seen despite my best efforts. After finding some more crab claws it was time to head out. On the trek to the car, I spotted a Trigonia whitneyi? clam, maybe from the upper Glen Rose. I'm not sure what species this is. I see Polyacrodus aff. parvidens is described form the Texas Albian up north. Other than that, there doesn't seem to be much info. I've seen some discussion on Polyacrodus brevicostata being a possibility as well. Top L to R: Trigonia whitneyi? and Pagurus banderensis Bottom L to R: Amiid tooth, Pycnodont teeth, Isocrinus annulatus It seems my streak of urchin unluckiness has continued, but I'll take a Polyacrodus any day of the week!

Hi all, I have a ton of teeth gathered from Purse state park and I’m not sure how to ID. Can anyone please help with these few? Hoping to learn how to do it myself eventually

I know its small but I found this tooth a while back and had forgotten about it so while looking through my trips smaller teeth I found 3 Carcharoides totuserratus which i didn’t know were rare until watching one of blackriverfossils videos. So I was wondering what kind of tooth this is and if anything rare? The last photo is the Carcharoides totuserratus I was talking about.

I just got a package today of fossils from Morocco. Most were just your common mosasaur and otodus teeth, etc. But this one just doesn't look right. Can someone please help me identify it? It looks like a rather wide Otodus tooth but has a prominent ridge running down the middle. It also has a very large root and the tooth sits on quite an angle from the root. Appreciate any help. It is 2 1/2 cm across at the root.

Hi all, For a few months now, I occasionally go searching for shark/ray teeth in an old industrial area in Aruba. I found hundreds of smaller shark teeth (probably carcharhinus) and a handful of very cool & much larger teeth (likely otodus angustidens). This morning, I went walking the dogs there and stumbled upon a chunk of a much larger tooth! Could it be the megalodon? it could be a larger specimen of an O. Angustidens but the proportions are not quite the same… I'll let the experts judge for themselves. The (almost) complete O. Angustidens tooth in the middle is 2’1 inches (5,3 cm) long.
