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]]的[[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.

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,生活在上白垩世至中新世(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。
分类关系
[编辑]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的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。Groeberia和Vintana两个属都具有奇特的轭骨凸缘,这与诸如地懒的异关节类相似;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]
