Hi everyone, I'm Roger. I need some advices to proceed with the preparation of vertebrate material from Cretaceous marine sandstones of the Parras Basin in northeastern Mexico. I have some isolated mosasaurid centra with adhered matrix (mainly sandstone, as well shale) and some tiny shark teeth embedded in sandstone. I seek to use chemical methods. I have heard of the use of dimethyl sulfoxide but have never actually used it, if anyone has experience with this reagent I would love to hear your feedback. I am not opposed to working with mechanical methods, but I do not have the nece

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.
