MarcoSr Posted June 1, 2014 Share Posted June 1, 2014 I want to thank Jamie for sending me Cretaceous, Cenomanian matrix from the Lincoln Limestone Member of the Greenhorn Formation of Kansas which contained the specimens in this post. This matrix had a good density of shark, ray and fish teeth. Specimens ranged in size from .4mm to 13mm. I am posting below pictures of a small number of the nicer and more unusual specimens which I found. If you place your cursor on a JPEG image you will see the file name which will have the specimen id as best that I can determine and the specimen size. Breaking down the Lincoln Limestone required an original cycle of boiling water to remove some clay and then multiple freezing/boiling vinegar cycles. The wide diversity of micros in many formations is one of the reasons that I am an avid micro tooth collector. If anyone has or can collect good matrix with shark, ray, and fish micros please send me a PM. I really could use id help below. There is still a lot of flux with some of the major Cretaceous genera and unfortunately I can’t always get access to the latest papers. Shark teeth: Carcharias (Note there are multiple species of Carcharias present): Cretoxyrhina mantelli: Ptychodus (Note there are multiple species of Ptychodus present. I still have some difficulty identifying some Ptychodus specimens to the species level, especially posterior teeth): Continued in next reply.

MarcoSr Posted June 1, 2014 Author Share Posted June 1, 2014 (edited) Squalicorax (Note there are multiple species of Squalicorax present. Squalicorax is still very poorly described and needs a lot of further study): Some shark teeth that I need Id help: I believe that these are some species of Squalicorax like pawpawensis or maybe a Pseudocorax: This tooth is really bizarre: Continued in next reply.

fossilized6s Posted June 1, 2014 Share Posted June 1, 2014 Wow, that is a very bizarre "shark" tooth. You've found some cool stuff once again Marco! Great job!

Auspex Posted June 1, 2014 Share Posted June 1, 2014 Your work with these various micro samples is building a real treasure chest of fascination, and is no doubt both ground-breaking and valuable.

jcbshark Posted June 1, 2014 Share Posted June 1, 2014 Great stuff here too! Some of the olive and orange colors look like they're straight out of bone valley! Very nice! Every once in a great while it's not just a big rock down there! Link to comment Share on other sites More sharing options...

Al Dente Posted June 2, 2014 Share Posted June 2, 2014 Nice teeth.

We are privileged in the opportunity to see it first hand, and so well presented! Chas Hopefully more folks will get interested in these faunas and these micro teeth. There aren't a lot of folks studying and describing them in the US. Maybe because it is so difficult with some to break down the matrix to get the real micros out.

MarcoSr Posted June 2, 2014 Author Share Posted June 2, 2014 That last twisted fish tooth looks pretty freaky also. Always a great presentation Marco.

MarcoSr Posted June 2, 2014 Author Share Posted June 2, 2014 Awesome work. Kyle Definitely different from the awesome work that you and your dad are doing with your marine mammal and reptile specimens. Both require a lot of time and patience. Luckily what I do doesn't require the skill level to piece a specimen back together. Marco Sr. "Any day that you can fossil hunt is a great day."

I'm definitely interested, but i don't know many people in this field just yet. So any leads are helpful. Charlie Patrick used to make yearly trips to Morocco which he no longer does any more. He never really sold his matrix but traded it for other matrix. Patrick has been pretty consumed the last year with working on his new house so he hasn't done much with getting even local matrix from Belgium and The Netherlands. He has a friend Yoeri who may still be making trips to Morocco. However shipping costs have gone up substantially in the last few years. Patrick and I now only send well processed matrix with dense fossils to each other and even with that it is becoming cost prohibitive. Small USPS packages cost around $25, medium around $50. and large over $80 for me to ship to Europe so I don't ship much these days. Marco Sr. "Any day that you can fossil hunt is a great day."

PFOOLEY Posted June 2, 2014 Share Posted June 2, 2014 These are very interesting specimens. Excellent documentation, Marco. I am especially intrigued with the cartilage specimen. I have never seen something like that before...very cool. Thank you for your efforts in sharing these tiny treasures. "I am glad I shall never be young without wild country to be young in.
