... that highlights from the history of dromaeosaurid research include a skeleton of Velociraptor preserved in combat with a Protoceratops, the gigantic Utahraptor, and tiny four-winged Microraptor?
... that unlike its closest living relatives, lemurs and lorisoids, Djebelemur from Eocene Africa probably lacked a toothcomb?
... that multiple Leptocleidus skeletons have been found preserved as gemstone quality opal over the course of the history of plesiosaur research?
... that lemurs (pictured) are primates that evolved and diversified on the island of Madagascar after arriving there at least 56 million years ago on a raft of vegetation?
... that in addition to some isolated teeth and a jaw fragment, the Mesozoic mammals of Madagascar include the most complete mammalian skeleton known from the Mesozoic of Gondwana?
