Abstract Although detailed anatomical descriptions of skull morphology are available for representatives of many mammalian orders, no such descriptive work exists for bats, a group that comprises over 20% of extant mammalian species. [] Key Method Based on a series of specimens of Pteropus lylei, we describe the skull as a whole and the morphology of external surfaces of 24 bones (7 rostral, 16 cranial, plus the mandible) and 17 teeth.

The Internal Nasal Skeleton of the Bat Pteropus lylei K. Andersen, 1908 (Chiroptera: Pteropodidae)

It is shown that, despite terminological discrepancies across studies, homologies are straightforward to establish among these taxa and so comparative or phylogenetic studies may benefit from inclusion of turbinai characters.

On the Cranial Osteology of the African Palm Civet, Nandinia binotata (Gray, 1830) (Mammalia, Carnivora, Feliformia)

The external and endocranial surfaces of the skull of the African palm civet, Nandinia binotata, are described and illustrated in detail based on 30 specimens and comparisons are made with three extant carnivorans.

An Anatomical and Phylogenetic Study of the Osteology of the Petrosal of Extant and Extinct Artiodactylans (Mammalia) and Relatives

It is shown that in many ways the osteology of the hippopotamid ear resembles that of certain stem cetaceamorphans more than it resembles the ear regions of suines (pigs and peccaries), and shortest trees indicate that these similarities are convergent.

Comparative Basicranial Anatomy of Extant Terrestrial and Semiaquatic Artiodactyla

  • M. O'Leary

    Bulletin of the American Museum of Natural History
  • 2016
Exemplar species from the four major extant terrestrial and semiaquatic artiodactyla clades are described and the anatomy of the ear region with the auditory bulla both in place and removed and the basicranium is illustrated.

On the Treeshrew Skull (Mammalia, Placentalia, Scandentia)

ABSTRACT Skull anatomy other than the ear region of the pen-tailed treeshrew, Ptilocercus lowii Gray, 1848 (Ptilocercidae), is described and illustrated in detail based on 11 specimens from the

Cranial anatomy of an Eocene notoungulate mammal from northwestern Argentina with special reference on the ear region

Abstract A detailed anatomical analysis is here presented focused on a notoungulate skull recovered from sediments of the lower part of the Quebrada de los Colorados Formation (LC I; late middle

Petrosal Anatomy of the Nine-Banded Armadillo, Dasypus novemcinctus Linnaeus, 1758 (Mammalia, Xenarthra, Dasypodidae)

Quite a few similarities are found between the petrosals of D. novemcinctus and the chiropteran Pteropus livingstonii Gray, 1866, which in light of the divergent phyletic affinities and biologies of these animals are remarkable convergences.

Endocranial structures of Chiroptera (Mammalia) : contribution from fossils

Bat fossil endocasts have been little studied in the literature (nine published works, only one in the XXI century), and macromorphology of the brain of extant bats has only been characterized at the

On the Cranial Osteology of the Lagomorpha

Comparisons of selected craniomandibular features made between O. princeps, R. diazi, and the following additional leporids support various hypotheses of phylogenetic relationships among the studied taxa.

Cranial Morphology of a Pantolestid Eutherian Mammal from the Eocene Bridger Formation, Wyoming, USA: Implications for Relationships and Habitat

The most complete known skull of a pantolestine, Pantolestes longicaudus (YPM 13525), is described here and compared to potential close fossil relatives and extant mammals and Semicircular canal morphology differs from that of two likely terrestrial Paleocene mammals, Aphronorus and Eoryctes.




The cranial anatomy of the Mongolian Late Cretaceous multituberculate Kryptobaatar dashzevegi is described based on exquisitely preserved specimens collected from Ukhaa Tolgod and Tugrugeen Shireh in the Gobi Desert by joint expeditions of the American Museum of Natural History and the Mongolia Academy of Sciences, confirming the absence of several elements and the presence of several controversial elements.


Comparisons with other extinct and extant taxa support a position for Zalambdalestes within Eutheria but outside the crown-group Placentalia, and such primitive features as the last upper incisor in the maxilla, nasals broadly expanded posteriorly to contact the lacrimals, and the position of the glenoid fossa on the zygoma and not the braincase proper is reported previously.

Taxonomy and biogeography of African Fruit Bats (Mammalia, Megachiroptera). 1. General introduction; material and methods; results: the genus Epomophorus Bennett, 1836

This first part of a revision of African fruit bats contains a short general Introduction and a section Materials and Methods, both pertaining to all parts — as are the first remarks under Results —,

A new species of Rousettus (Chiroptera : Pteropodidae) from Lore Lindu, Central Sulawesi

The survey resulted in the collection of four specimens of Rousettus (Megachiroptera) in the swamp forest of Kenawu village, Lindu Lake, Lore Lindu National Park, which represent a new species, described in the present paper.

Petrosals of Late Cretaceous marsupials from North America, and a cladistic analysis of the petrosal in therian mammals

ABSTRACT Ten isolated petrosals of Late Cretaceous marsupials belonging to three types—A, B, and C—are described from the Lance Formation of Wyoming and the Bug Creek Anthills of Montana. These are

Cranial evidence for the monophyletic origin of bats. American Museum novitates ; ; no. 2911.

These, combined with the 16 derived features of the postcranial anatomy and fetal membranes cited in previous studies, strongly support the inclusion of megaand microchiropterans within the single order Chiroptera and are not congruent with the recent hypothesis that megachiropteran (and dermopterans) are more closely related to primates.

Homologies of the Prootic Canal in Mammals and Non-mammalian Cynodonts

The term prootic canal is proposed to be restricted to the canal enclosing the prootic sinus (middle cerebral vein) of extinct “non-tribosphenic” mammals.

Taxonomy and biogeography of African fruit bats (Mammalia, Megachiroptera). 4. The genus Rousettus Gray, 1821

All African Rousettus species are characterized and their distributions, including many new records, and geographical variation are analyzed, suggesting that sexual dimorphism may be at least partly responsible for the “geographic” variation noted by Kock (1978).

Further examination of the basicranial anatomy of the megachiroptera: a reply to A.J. King.

To address King's claims, the two characters in question (regarding the tegmen tympani and ramus inferior of the stapedial artery) are documented here for Pteropus.

Molecular systematics of bats of the genus Myotis (Vespertilionidae) suggests deterministic ecomorphological convergences.

Molecular reconstructions support paleontological evidence that species of the genus Myotis had a burst of diversification during the late Miocene-early Pliocene epoch.
