Heteromorph posted a topic in Fossil IDIn late February I went to a site in the Middle/Upper Santonian stage of the Bruceville Chalk Marl Formation, Austin Group, in Ellis county, Texas. While at the site I found a few inoceramids, possibly an anaptychus, and a chunk of rock that looks like it could have mollusk grazing traces on it. Then today I was organizing my collection and picked up the rock with the possible grazing traces. While I was handling the rock I happened to look at the bottom of it and spotted a small Squalicorax sp. tooth, my first tooth from the Santonian. It is 11 mm long and is pretty complete, with the left side of the root being exposed. I am not sure about the right side of the root, but it may still be there under the matrix. I have been trying to put it to a species. From looking through Welton and Farish’s book as well as elasmo.com the most likely candidates seem to be the two paleo-buckets S. “falcatus” and S. “kaupi,” and the species S. lindstormi. I am not terribly familiar with fossil shark teeth, so I am very curious what the more informed members of this forum can say about what species this could be. I am also wondering if the first picture could be of mollusk grazing traces. Would it be a good idea to try to prep it out further? And if so, what would a good strategy be with chalky/marly matrix?
