From New Latin Euthēria, from Greek eu- + thēria, plural of thērion beast.
CHE SIGNIFICA EUTHERIAN IN INGLESE
Eutheria
L'Eutheria è una delle due clavate di mammiferi con membri esistenti che divergono nel Cretaceo anteriore o forse nel tardo Jurassico. L'altro è la Metatheria, che include i marsupiali, la maggior parte dei quali ospitare i loro neonati in sacchetti. Fatta eccezione per l'opossum Virginia, che è un metatarso, tutti i mammiferi indigeni dell'Europa, dell'Africa, dell'Asia e dell'America settentrionale del Messico sono eutheriani. Gli eutheriani estinti, il loro ultimo antenato comune e tutti i discendenti estinti di quel predecente sono placentali, nel gruppo Placentalia. Gli eutheriani si distinguono dagli esseri senesi da varie caratteristiche dei piedi, delle caviglie, delle mascelle e dei denti. Una delle principali differenze tra eutheria placentare e non placentare è che le placentali non presentano ossa epipubiche, presenti in tutti gli altri mammiferi fossili e vivi. La più antica specie eutheria conosciuta è la Juramaia sinensis datata 160 milioni di anni fa dalla Jurassic in Cina. Il nome "Eutheria" è stato introdotto da Thomas Henry Huxley nel 1880, inteso ad includere un gruppo più ampio di Placentalia.
definizione di eutherian nel dizionario inglese
La definizione di eutero nel dizionario è di, relativa o appartenente all'Eutheria, una sottoclasse di mammiferi che hanno tutti una placenta e raggiungono uno stato avanzato di sviluppo prima della nascita. Il gruppo include tutti i mammiferi tranne i monotremi ei marsupiali. L'altra definizione di eutero è qualsiasi mammifero eutero.

Faunal and Floral Migration and Evolution in SE Asia-Australasia

Hybrid Zones and the Evolutionary Process
JEREMY B.SEARLE It has long been realized that many closely related species
of eutherian mammals differ in karyotype, sometimes to an extreme degree (e.g.,
Bush et al., 1977; White, 1978a; Bengtsson, 1980). Furthermore, these species ...

The Beginning of the Age of Mammals
North American Montanalestes (Fig. 6.3B), from the Albian (about 110 Ma) of
Montana, is the oldest North American eutherian-like form. It is known from a
lower jaw with four or five premolars (the precise number is uncertain) and three
molars.

The Age of Everything: How Science Explores the Past
The earliest known eutherian comes from China. It was described in 2002, based
on a well-preserved specimen consisting of a nearly complete skeleton and,
remarkably, imprints of the animals' fur. This creature, named Eomaia scansoria,

Marsupial Genetics and Genomics
Although much of the eutherian X chromosome is homologous to the marsupial X
, there is a region of the eutherian X (generally most of the short arm) that is
autosomal in marsupials, indicating that the eutherian sex chromosomes were ...
