How to tell apart mosasaur and Enchodus teeth? This fragment is 2 mm in length. It has longitudinal striations (not visible on photo) and at least one cutting edge (there might be a second on the other side, but some surface is missing there, and a bit of sediment is adhering), the cross section seems to be oval-to-irregular (but see comment above). The lower part is witish, the upper - redish. Sorry for the poor quality picture. Lower Campanian, marine, southern Poland.

PeterNakridletia_ord1.n._-_pterosaur_parasites.pdf Less than 1 Mb. I like to post items which throw a new light onto the fossil record, and/or generally clarify /obscure (for whatever reason) matters. A really terrific paper!!Recommended! Mesozoic and Paleozoic parasitism, and mutualism, and commensalism, and trophic amensalism, ETC. Paleopathology, we know way too little about ecological interactions in the past.
