Miacids
Miacids are extinct primitive carnivoramorphans within the family Miacidae that lived during the Paleocene and Eocene epochs, about 62–34 million years ago. Miacids existed for approximately . Miacids are thought to have evolved into the modern carnivorous mammals of the order Carnivora. They were small carnivores, superficially marten-like or civet-like with long, lithe bodies and long tails. Some species were arboreal, while others lived on the ground. They probably fed on invertebrates, lizards, birds, and smaller mammals like shrews and opossums. Their teeth and skulls show that the miacids were less developed than modern carnivorans. They had carnivoran-type carnassials, but lacked fully ossified auditory bullae (rounded protrusions). Classification Miacidae as traditionally conceived is not a monophyletic group; it is a paraphyletic array of stem taxa. Traditionally, Miacidae and Viverravidae had been classified in a superfamily, Miacoidea. Today, Carnivora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quercygale
''Quercygale'' is an extinct genus of Miacidae, primitive carnivores that lived during the Eocene. The genus contains four species: ''Q. angustidens'', ''Q. hastingsae'', ''Q. helvetica'', and ''Q. smithi''. Phylogenetic analysis of the basicranial morphology of miacid carnivoramorphans suggests ''Quercygale'' is the most advanced miacid and sister to crown group Carnivora, predating the split between Feliformia Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats (large and small), hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Canifor ... and Caniformia., although another recent study places them as a stem group within Feliformia.

Paroodectes
''Paroodectes'' is a miacid animal that lived during the early Eocene (ca. 50 million years ago) in the rain forests and swamps of the present-day Germany. It was a prehistoric predator that had the size and the appearance of a cat and was well adapted to climbing, as is apparent from its limbs, joints and shoulder bones. Its long tail gave balance for tree climbing and jumping from branch to branch. ''Paroodectes'' probably hunted insects, rodents and small primates in the tree tops. Only one species of ''Paroodectes'' (''P. feisti'') has been found, and this was at the Messel Pit located southeast of Frankfurt, Germany. The pit was formed during the Geiseltalian Period (or Middle Eocene) about 50 million years ago. The fossil was found by private collector Otto Feist in 1974. It was described in 1980 by Rainer Springhorn who said the following about the species: "The odontological features of the Messel-Miacid are nearest to the new world genus Oodectes from the Bridger Basin ( ...
