miacis造句

• Christian Mathis has defined to make a difference between the miacids from Europe and the American genus " Miacis ".
• By the early Eocene the arctocyonids were supplanted by the hyaenodonts, mesonychians and the early carnivorans such as " Miacis ".
• It was originally interpreted it as a miacid and named " Miacis australis ", however recent research has suggested it is an early amphicyonid.
• He is commemorated in the genus " Hargeria ", a fossil bird, and the species " Miacis hargeri ", an extinct carnivorous mammal.
• "Miacis " species were five-clawed, about the size of a weasel ( ~ 30 cm ), and lived on the North American and European continents.
• What is the name of the paper in which Edward Drinker Cope described the species " Miacis parvivorus " ? mt " ) 17 : 43, 12 July 2008 ( UTC)
• This would have been a member of the older ( and now entirely extinct ) miacid Family Miacidae, probably a member of the Genus Miacis, and probably lived around 42 50 million years ago.
• Analysis of skeletal morphology suggests it is most closely related to another taxon previously attributed to Miacidae, " Miacis cognitus ", and the well known New World amphicyonid, " Daphoenus ".
• They retained some primitive characteristics such as low skulls, long slender bodies, long tails, and short legs . " Miacis " retained 44 teeth, although some reductions in this number were apparently in progress and some of the teeth were reduced in size.
• It had retractable claws, agile joints for climbing, and binocular vision . " Miacis " and related forms had brains that were relatively larger than those of the creodonts, and the larger brain size as compared with body size probably reflects an increase in intelligence.
• Like many other early carnivoramorphans, it was well suited for an arboreal climbing lifestyle with needle sharp claws, and had limbs and joints that resemble those of modern carnivorans . " Miacis " was probably a very agile forest dweller that preyed upon smaller animals, such as small mammals, reptiles, and birds, and might have also have eaten eggs and fruits.
• Hesperocyonine canids first appeared in North America, and the earliest species is currently dated at 39.74 mya, but they were not represented in Europe until well into the Miocene, and not into Asia and Africa until the Pliocene . " Miacis " and Amphicyonidae were the first of the caniforms to split from the others and are sometimes considered to be sister groups to Ursidae, but the exact closeness of Amphicyonidae and Ursidae, as well as Arctoidae to Ursidae, is still uncertain.
• :However, although we know of at least one species of Genus Miacis, " Miacis cognitus ", we cannot be sure if this particular species was the Most Recent Common Ancestor of the carnivores, or whether it was a ( probably similar ) sister species, of which fossils may not have yet been ( and may never be ) found-only a small fraction of all extinct species, with or without descendents, have been found as fossils, as fossilisation is a very rare event.
