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.

Miacis, genus of extinct carnivores found as fossils in deposits of the late Paleocene Epoch (65.5–55.8 million years ago) to the late Eocene Epoch (55.8–33.9 million years ago) in North America and of the late Eocene Epoch in Europe and Asia.

2024年5月21日 · Miacids are an extinct group of mammalian carnivores that gave rise to cats, bears, dogs, skunks, mongooses, hyenas, and all other felids and canids.

2013年4月1日 · The study of the “miacids” from Le Quesnoy increases the generic diversity of the “Miacidae” during the beginning of the Early Eocene with the identification of Vassacyon taxidiotis.

Miacis ("small point") is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America from the early to middle Eocene. [4][5][6] Miacis was five-clawed, about the size of a weasel (~30 cm), and lived on the North American continent.

2018年6月27日 · Miacidae (suborder Fissipedia, super-family Miacoidea) An extinct mammalian family, known from the Palaeocene and Eocene, which is believed to be directly ancestral to the modern carnivores and which itself evolved directly from insectivore stock.

Miacoids were mostly small carnivorous mammals, superficially reminiscent of martens or civets. They probably fed on invertebrates, lizards, birds and smaller mammals like shrews and rodents, while others may have been insectivores. Some species …

These oldest-known fissipede carnivores are described in detail, the classification is revised, and notes on their probable ecology and known geographic and stratigraphic distribution are included. A list of characters believed primitive for miacids is presented, together with some discussion of possible miacid ancestry.

2022年10月10日 · From their initial discovery in the late 19 th century, through to the late 20 th century, these carnivoramorphs were traditionally all lumped together under the name “miacids“. As a result the group quickly turned into a big wastebasket taxon of similar-looking animals, all united more by just not being true carnivorans than by any shared ...
