we use lasers to vaporize small amounts of enamel from fossil teeth (like this troodontid allowing the released gases to be analyzed for their chemical composition?

This can reveal info about the diet, habitat, and physiology of extinct animals.

For congratulation to our Master student who finished today (co-supervised with ). A very nice work on the morphology of the and what we can say about it (phylogeny, ontogeny, allometry).

Time for We like to think of tooth replacement as a tidy process. But here are 4 cross sections of jaws that show chunks of older teeth that were left behind in the bone! Happens a lot in animals that continually replace their teeth, like these extinct synapsids.

A fun comparison for Pterodactylus restored by Jean Hermann in 1800 vs. Pterodactylus restored by me, 220 years later. Hermann's pterosaur is the oldest known 'legit' piece of palaeoart - a fossil-based life reconstruction based on science, not mythology.
