leopards, lions, and tigers
how long did ancestral and extant felids arise
-anc: 20-8 mya
-ex: arose form a common ancestor ~10-11 mya
proaliurus
-25 mya
-first felid like animal in the fossil record
pseudaelurus
-20-8mya
-ancestral to:
extant cats
extant panters
extinct cats (sabre toothed)
where did cats originate
SE asia (11mya)
why were cheetahs thought to be in a different subfamily at one point
-previously was considered a different subfamily but now considered felinae
-grouped in the puma lineage
-the claws on the cheetah remain out and add to its ability to make sharp turns and bends when running at a great speed
-in all other cats claws retract
why to pantherinae roar
-the hyoid bone is connected to the base of the tongue and the larynx
-in roaring cats part in cartilage
-in all other cats, it is bone
-snow leopards are the only panther that do not roar
-they also have different vocal cords (square for roaring and triangle for others)
-this bone possibly causes purring in other cats
