Middle Jurassic flea fossils. They are 10x the size of modern fleas!
Velociraptors were nocturnal, from a report out today in the journal Science. The researchers examined the scleral rings of more than 160 living species, including birds and reptiles, each with known activity patterns — some that are active at night, others during the day and still others that can swing either way. The structure of the velociraptor’s ring matches up to those that are nocturnal. Surprising, but makes total sense.
