Hyainailouros ("hyena-cat") is an extinct paraphyletic genus of hyaenodont belonging to the family Hyainailouridae that lived during the Early to Middle Miocene from 22 to 15 million years ago. This genus comprises at least three species spread across Afro-Eurasia. Currently, there’s a debate whether or not Megistotherium was synonymous to Hyainailouros or a separate genus entirely. The genus currently consists of at least 3 species, H. bugtiensis, H. sulzeri, and H. napakensis. H. sulzeri was the type species of and the largest species within the genus, weighing 500 kg (1,100 lb). On the other hand, H. napakensis was believed to have been the smallest weighing 202–271 kg (445–597 lb), the…

Ape Ancestor (About Seven Million Years Ago). Abstract If you had been born as one of your ancestors who lived seven million years ago, you would have been an ape living in an African forest. This ancestor would also be the ancestor of the chimpanzees and bonobos that still live in African forests. You would have already possessed some of the characteristics that make humans an unusual animal. You would have had a large brain (but not nearly as large as the brain you have now). You would have taken a long time to grow and reach maturity (but not has long as it took you as a human). And, by watching your mother as she foraged and negotiated her social life, you would have gained a head start…

Whence the beardogs? Reappraisal of the Middle to Late Eocene '<i>Miacis</i>' from Texas, USA, and the origin of Amphicyonidae (Mammalia, Carnivora).. The Middle to Late Eocene sediments of Texas have yielded a wealth of fossil material that offers a rare window on a diverse and highly endemic mammalian fauna from that time in the southern part of North America. These faunal data are particularly significant because the narrative of mammalian evolution in the Paleogene of North America has traditionally been dominated by taxa that are known from higher latitudes, primarily in the Rocky Mountain and northern Great Plains regions. Here we report on the affinities of two peculiar carnivoraform…
