There are three known [[family (biology)|families]] within Gondwanatheria. The family Sudamericidae was named by Scillato-Yané and Pascual in 1984, and includes the vast majority of named taxa. The family Ferugliotheriidae was named by [[José Bonaparte]] in 1986, and includes one genus, ''[[Ferugliotherium]]'', and possibly a few other forms like ''[[Trapalcotherium]]''. [[Groeberiidae]], originally interpreted as [[paucituberculate]] [[marsupials]], has since been understood as gondwanatherians, though only the type genus, ''[[Groeberia]]'', has been examined as such.<ref name="Nicolás R. Chimento 2014">{{cite journal |authors=Nicolás R. Chimento, Federico L. Agnolin and Fernando E.

冈瓦那兽目下有3个已知的科,其中Sudamericidae科由Scillato-YanéPascual1984年命名,包含该类群的绝大多数部分。Ferugliotheriidae科由José Bonaparte1986年命名, 包含''Ferugliotherium''一个属,而且可能包括诸如''Trapalcotherium''等其他类群。Groeberiidae科最开始被认为是Paucituberculate目的[[有袋類|有袋类]],之后因该科中''Groeberia''属经检验后被归入冈瓦那兽目,所以整个科也被归入冈瓦那兽目。<ref name="Nicolás R.

Gondwanatheres known from cranial remains almost universally have deep, robust snouts, as befitting their specialised herbivorous lifestyle. ''[[Groeberia]]'' and ''[[Vintana]]'' both possess bizarre [[jugal]] flanges similar to those of [[xenarthra]]ns like [[ground sloth]]s, though they had a palinal (front-to-back) chewing method as in most allotheres and unlike almost any therian.<ref>Krause, David W.; Hoffmann, Simone; Wible, John R.; Kirk, E.

从头部骨骼化石得知,冈瓦那兽目动物普遍具有深长而强壮有力的口鼻部,这有利于它们营专一的[[植食性]]生活。''Groeberia''和''Vintana''两个属都具有奇特的轭骨凸缘,这与诸如[[地懒]][[异关节总目|异关节类]]相似;但这两个属的咀嚼方式与大多数[[异兽亚纲]]动物一样为后移式(由前向后),而这一点与几乎所有的[[獸亞綱|兽亚纲]]动物都不同。<ref>Krause, David W.; Hoffmann, Simone; Wible, John R.; Kirk, E.

于梅法拉诺[[组 (地质学)|组]]发现的具关节的样本,为研究者提供了有关这一类动物的非头部骨骼的深入信息。其中奇异而独特的特征包括:中间外侧扁平且前后弯曲的胫骨、具双滑车的[[距骨]]、发育完全的[[肱骨]]滑车,以及异常多的[[脊椎|躯椎]]。这一新类群拥有19节与肋骨相连的脊椎(胸椎)和11节不与肋骨相连的脊椎(腰椎)。除了这些衍生特征之外,这种来自[[马达加斯加]]的哺乳动物还拥有镶嵌的[[胸带]]形态:其前乌喙骨缺失,乌喙骨高度发达(形成一个扩大的过程,占关节窝的一半),间锁骨小,而且胸锁关节似乎可活动。有A ventrally facing glenoid and the well-developed humeral trochlea suggest a relatively parasagittal posture for the forelimbs. Remarkable features of the hind limb and pelvic girdle include a large obturator foramen similar in size to that of [[theria]]ns, a large parafibula, and the presence of an [[epipubic]] bone.<ref>HOFFMANN, Simone, THE FIRST POSTCRANIAL REMAINS OF A GONDWANATHERIAN MAMMAL, October 2016</ref>
An articulated specimen found in the [[Maevarano Formation]] offers insight to the postcranial skeleton of these animals. Among the bizarre and unique features are a mediolaterally compressed and antero-posteriorly bowed tibia, a double trochlea on the astragalus, a fully developed humeral trochlea, and an unusually high number of trunk vertebrae. The new taxon has at least 19 rib-bearing (thoracic) and 11 non-rib-bearing (lumbar) vertebrae. Aside from these derived features, the Malagasy mammal has a mosaic pectoral girdle morphology: the procoracoid is lost, the coracoid is extremely well developed (into an enlarged process that contributes

to half of the glenoid fossa), the interclavicle is small, and the sternoclavicular joint appears mobile. A ventrally facing glenoid and the well-developed humeral trochlea suggest a relatively parasagittal posture for the forelimbs. Remarkable features of the hind limb and pelvic girdle include a large obturator foramen similar in size to that of [[theria]]ns, a large parafibula, and the presence of an [[epipubic]] bone.<ref>HOFFMANN, Simone, THE FIRST POSTCRANIAL REMAINS OF A GONDWANATHERIAN MAMMAL, October 2016</ref>

冈瓦那兽目学名:Gondwanatheria,亦可称为冈瓦纳兽目)是哺乳动物中一个已经灭绝的目,生活在上白垩世中新世(而且可能更早,如果将Allostaffia划为该目的成员[3])的南半球,包括南极洲。该类群为人所知的仅有数颗分离的牙齿,几片下颌骨,两块不完整的头骨和一块完整的头骨。[4]正是因为这种零碎的知识,其分类地位不甚清晰。

该类群分类关系的不明确持续了几十年,其最开始被认为是早期的异关节总目动物,一种“无齿”的哺乳动物,接近现代的食蚁兽。随后的多个不同研究认为它们属于异兽亚纲,接近多瘤齿兽目,甚至可能真正属于多瘤齿兽目,比Cimolodonta亚目更接近于Plagiaulacida亚目。[1][5][6][7]然而,一项最近的研究表明,它们与贼兽目有关,并将它们列入非哺乳动物的犬齿兽亚目[8]

冈瓦那兽目下有3个已知的科,其中Sudamericidae科由Scillato-Yané及Pascual于1984年命名,包含该类群的绝大多数部分。Ferugliotheriidae科由José Bonaparte于1986年命名, 包含Ferugliotherium一个属,而且可能包括诸如Trapalcotherium等其他类群。Groeberiidae科最开始被认为是Paucituberculate目的有袋类,之后因该科中Groeberia属经检验后被归入冈瓦那兽目,所以整个科也被归入冈瓦那兽目。[1]

另有化石在印度马达加斯加南极被发现。一个可能为Ferugliotherium属物种的化石在墨西哥马斯特里赫特期地层中被发现,使得此类群的分布范围扩展到北美洲[9]

中新世(Colhuehuapian英语Colhuehuapian期)的属Patagonia是该类群已知年代最近的代表。[1]

生物学

[编辑]

从头部骨骼化石得知,冈瓦那兽目动物普遍具有深长而强壮有力的口鼻部,这有利于它们营专一的植食性生活。GroeberiaVintana两个属都具有奇特的轭骨凸缘,这与诸如地懒异关节类相似;但这两个属的咀嚼方式与大多数异兽亚纲动物一样为后移式(由前向后),而这一点与几乎所有的兽亚纲动物都不同。[10][1]大多数冈瓦那兽目动物是专一的牧食生物,它们是最早专一于食草的哺乳动物,远早于兽亚纲动物(Groeberiidae科与Ferugliotheriidae科除外,因为它们缺乏高冠齿,其植食性可能更广泛)。

于梅法拉诺发现的具关节的样本,为研究者提供了有关这一类动物的非头部骨骼的深入信息。其中奇异而独特的特征包括:中间外侧扁平且前后弯曲的胫骨、具双滑车的距骨、发育完全的肱骨滑车,以及异常多的躯椎。这一新类群拥有19节与肋骨相连的脊椎(胸椎)和11节不与肋骨相连的脊椎(腰椎)。除了这些衍生特征之外,这种来自马达加斯加的哺乳动物还拥有镶嵌的胸带形态:其前乌喙骨缺失,乌喙骨高度发达(形成一个扩大的过程,占关节窝的一半),间锁骨小,而且胸锁关节似乎可活动。有A ventrally facing glenoid and the well-developed humeral trochlea suggest a relatively parasagittal posture for the forelimbs. Remarkable features of the hind limb and pelvic girdle include a large obturator foramen similar in size to that of therians, a large parafibula, and the presence of an epipubic bone.[11]
