Hey y'all, I went to POC for the first time yesterday and came back with some stuff I need help ID'ing. 1. Shark teeth - Cretodus crassidens? 2. Large shark tooth - Cretoxyrhina? 3. shark tooth - Scapanorhynchus? 4. Enamel/tooth frag - mosasaur? 5. shark tooth - Cretolamna appendiculata? All scale bars = 1 cm. The enamel (4) is < .5 cm in length. 4 is definitely not shark - too thick - and reminds me of crocodiles, but I haven't heard of any crocs there. I also found another mosasaur tooth frag. I know this can be really difficult, so I really appreciate your help!

Went on a hunt with my son this past weekend. Had a friend join us for part of the day. We hit a part of the creek that does not get hit too hard. Was just telling her that I had found some large partial Cretodus earlier in this spot when she tells me she found a great tooth. She wasn’t kidding. Best tooth I have seen all year.

Hi everyone! So it has been a busy week for me, as I have things to post but haven't found the time. I just got back from Gemworld 2017 and I would like you opinion on my one and only purchase. I went to the show with the mindset that if I bought anything at all it had to be something special. I normally do not buy fossils. So after walking around and looking at many interesting specimens, what caught my eye was a Cretodus crassidens tooth from South Dakota in matrix. I have wanted one of these for awhile. The tooth is pretty nice. It is all intact. But there are two cracks which run though the tip of the root above one of the cusps. As an added bonus there is a smaller Cretodus as well as a few Squalicorax falcatus teeth on the top and bottom of the piece. There also appears to be possible bone and fish teeth. I paid $97. I know that Cretodus teeth are sought after and can demand a fairly high price. Because don't normally buy, I would just like to know if you guys think it was a good purchase. I don't know if I would have paid that much for the Cretodus by itself , but with all the other teeth in the matrix It was hard to pass up. Here are some pics. I can try to take some close-ups later if anyone wants. Thanks Dave

Hola! I decided to get up early this morning to head over to Post Oak Creek to see if I could make up for the lack of production on the NSR (North Silted Ridges). I headed over to my favorite spot to sift and after seeing a tooth or two lying on the surface, I decided to walk the entire gravel bar to see what else may be up on top. I came across a monster horse shoe (this guy must have been a beast) and jokingly thought to myself that it meant I was going to have a good day. Well, that joke turned into reality. I walked past where I found the horse shoe and this honker was lying in wait for someone to find. This is the biggest shark tooth by far for me. I felt like a kid on Christmas that just opened his dream present. I believe its Cretodus. Please correct me if I'm wrong. After gathering two 5 gallon buckets worth of gravel, I headed back toward the car and decided to take a breather (10 gallons of wet gravel weights more than 10 gallons of feathers ). While walking around I found the little bottle. I then walked over to another gravel bar and found my first mosasaur vert in the POC. If the POC had the size and quantity of mosasaur verts and teeth that the NSR does, I'd never leave Sherman. Speaking of the NSR, if you haven't been in awhile, you may want to wait. I spent about 6 hours out there this past Thursday and while there is some low lying water in the river and creek beds, all the gravel bars I saw were covered in silt. It's in serious need of a good heavy rain and I'm waiting till then before I go back out. David

Hello everyone. I found this guy last week in the Blue Hill Shale of Kansas. I immediatly thought it was a Cretodus crassidens as I found another one close by last year and have found several large Cretodus in the Blue Hill Shale. However when I got home I noticed that the cusplets appeared to be missing. Upon closer inspection I found that they were not missing/broken and the tooth was in perfect shape. I have about 8 of these anterior Cretodus teeth and all of cusplets or clear breaks where they were. This one does not. Could it be I am looking at something other than Cretodus (Cretoxyrhina?) or just an unusual Cretodus tooth? It's not a big deal, but I would like to know. Thanks in advance!

Hey everyone. Just wanted to share last weekends outing. Kind of funny, but in the course of two weeks I went from have never found a shark tooth to finding a dozen and now possibly hundreds. I went to another place in the Blue Hill Shale in Osborne county Kansas on an unexpected day trip with my father just to look around. Couldn't go to our new favorite spot because of deer season. Anyway, we found about a dozen nice teeth and a HUGE Cretodus tooth (my dad's first shark tooth ever). But the real interesting thing is that I found several small and very thin conglomerates of tiny shark and fish teeth as well as some vertibrate and various other parts and pieces. Hopefully you can get the idea from the pictures. It's pretty neat- hundreds of tiny teeth from various fish and sharks. Read about a similar find on Oceans of Kansas in Jewel county in he Blue Hill Shale. Here are a few photos. Dad's find on top- bigger than the one from last week and beautiful. Not sure, but isn't Credotus the biggest shark from Kansas?
