Plax Posted March 29, 2018 Share Posted March 29, 2018 How does one differentiate this from Cretolamna maraccana or is it biauriculata (sorry for the misspellings). Link to comment Share on other sites More sharing options...

It is 100% a Serratolamna serrata. Only a few have been found. A good way to distinguish them is by the unequal number and/or size of the cusplets when comparing the mesial and distal sides and by a small nutrient groove. The nutrient groove on your tooth looks like the right size for a Serratolamna; I initially thought it was larger based off of the original pic. The cusplets may also look a bit like Cretolamna cusplets (especially the primary cusplets on your tooth) since Serratolamna is related to Cretolamna.

Plax Posted March 29, 2018 Share Posted March 29, 2018 just wanted to know how Brad. Not arguing it is Cretolamna. Pics I see online look very confusing. 1 Link to comment Share on other sites More sharing options...

These teeth have more asymmetrical cusplets than Cretolamna maroccana; Serratolamna teeth are also narrower, more elongate, and less erect. C. maroccana has never been found before in NJ. 1 “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

sixgill pete Posted March 29, 2018 Share Posted March 29, 2018 Beautiful tooth. I have several of these from various Cretaceous sites here in North Carolina. I would not call them rare here. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
non-remanié Posted March 30, 2018 Share Posted March 30, 2018 cf. Cretalamna biauriculata maroccana can also be found in NJ. Also incredibly rare, probably a bit more so than S. serrata. 1 ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...

Do you possibly have any pictures of them from NJ? I would be interested in seeing some.
