Fun with Calvert Formation micros


Recommended Posts

We were very fortunate to get quite a bit of Calvert Formation micro matrix and some great teeth from @sharkdoctor. This is my first exploration of this formation and I am loving it. Lots of Carcharhiniformes material and it will take me a little time to ID some of Carcharhinus teeth but that is a good learning experience. I need the practice. 

 

The very fine matrix has been my favorite. I’ve found a few Scyliorhinus teeth, a few Squalus teeth and a few Mustelus teeth. Raja teeth are way more common than in STH. I’ve searched a lot of STH matrix and found 2 Skate teeth. It took me 10 minutes to find two in this mix. 

 

I have a lot more searching to do but I am really enjoying this.

So glad to see that you are enjoying this material. I forwarded the ID literature for these samples today. You'll notice that Brett doesn't put a genus on these little critters. However, he does note that there are likely to species of Squalus and goes so far as to call them Sp1 and Sp2.

Hi Aaron

 

I will check the reference out for sure. Two species of Squalus is interesting. I wonder if there might be multiple Catsharks too. I am certainly enjoying myself !
