Eurymylidae ( الإنجليزية )

المقدمة من wikipedia EN

Eurymylidae is a family of extinct simplicidentates. Most authorities consider them to be basal to all modern rodents and may have been the ancestral stock whence the most recent common ancestor of all modern rodents (crown rodents) arose. However, the more completely known eurymylids, including Eurymylus, Heomys, Matutinia, and Rhombomylus, appear to represent a monophyletic side branch not directly ancestral to rodents (Meng et al., 2003). Huang et al. (2004) have argued that Hanomys, Matutinia, and Rhombomylus form a clade characterized by distinctive features of the skull and dentition that should be recognized as a separate family, Rhombomylidae. Eurymylids are only known from Asia.

Classification

Modified from McKenna and Bell (1997) following generic taxonomy of Ting et al. (2002) and Huang et al. (2004)

Eurymylidae ( الإسبانية، القشتالية )

المقدمة من wikipedia ES

Eurymylidae es una familia extinta de los glires que vivieron desde el Paleoceno inferior al Eoceno medio en lo que ahora es Asia. Su posición filogenética dentro de los glires es controvertida: algunos la consideran ancestral de los roedores y otros una rama colateral de estos.

Eurymylidae ( الإيطالية )

المقدمة من wikipedia IT

Gli eurimilidi (Eurymylidae) sono una famiglia di mammiferi estinti, molto affini ai roditori. Vissero in Asia tra il Paleocene e l'Eocene (60 – 50 milioni di anni fa) in Asia, e da molti studiosi sono ritenuti molto vicini all'antenato dei roditori veri e propri.

Classificazione

Conosciuti principalmente per fossili della dentatura e del cranio, questi animali mostrano caratteristiche molto simili a quelle dei roditori, anche se più primitive. Le dimensioni non eccedevano quelle di un coniglio, e l'aspetto era forse simile a quello di un attuale pika (gen. Ochotona). I più completi resti di eurimilidi appartengono ai generi Eurymylus, Heomys, Matutinia e Rhombomylus; questi fossili mostrano chiaramente caratteri derivati in comune, e quindi rappresentano un gruppo monofiletico non direttamente ancestrale ai roditori (Meng et al., 2003). Altri studiosi (Huang et al., 2004) hanno ipotizzato che alcuni generi (tra cui Hanomys e i già citati Matutinia e Rhombomylus) possiedano caratteri distintivi nel cranio e nella dentatura tali da giustificare l'inserimento in una famiglia a sé stante, i Rhombomylidae. In ogni caso, entrambe le famiglie verrebbero raggruppate nel piccolo ordine dei mixodonti (Mixodonta). I mixodonti, attualmente, sono considerati il sister group dei roditori, nel gruppo dei semplicidentati.

寬臼獸科 ( الصينية )

المقدمة من wikipedia 中文维基百科

寬臼獸科學名Eurymylidae)是一滅絕單齒類。大部份學者都認為牠們是所有現今齧齒目的基底,且是齧齒目最後共同祖先的祖先。但是認識較多的原古兔屬曉鼠屬晨光獸屬菱臼獸屬似乎是一個非齧齒目直接祖先的單系群[1]另外有指曉鼠屬、晨光獸屬及菱臼獸屬是屬於同一分支,擁有獨特的頭顱骨齒式特徵。應分類為Rhombomylidae。[2]寬臼獸科只在亞洲被發現。
