This study is based on the examination of histological sections of specimens of different ages and of adult ossicles from macerated skulls representing a wide range of taxa and aims at addressing several issues concerning the evolution of the ear ossicles in marsupials. Three‐dimensional reconstructions of the ear ossicles based on histological series were done for one or more stages of Monodelphis domestica, Caluromys philander, Sminthopsis virginiae, Trichosurus vulpecula, and Macropus…

On the development of the chondrocranium and the histological anatomy of the head in perinatal stages of marsupial mammals
TLDR
Comparative studies of chondocranial development of mammals can benefit from a solid phylogenetic framework, research on non-classical model organisms, and integration with imaging and sectional data derived from computer-tomography.
Morphology of the Middle Ear Ossicles in the Rodent Perimys(Neoepiblemidae) and a Comprehensive Anatomical and Morphometric Study of the Phylogenetic Transformations of these Structures in Caviomorphs
The extinct clade of caviomorph rodents Neoepiblemidae includes forms that lived in South America from the early Miocene to Pliocene. Among them is Perimys. The exceptional preservation of ear…
Carpal ontogeny in Monodelphis domestica and Caluromys philander (Marsupialia).
TLDR
The aim of this work was to document adult form and the pattern of mesenchymal tissue condensation and formation of chondrification and ossification centers in the hand of two marsupials, and to find out whether there is sexual dimorphismus in the carpals, as has been reported for some didelphids.
Prenatal cranial ossification of the humpback whale (Megaptera novaeangliae)
TLDR
This study uses high‐resolution X‐ray computed tomography to reinvestigate humpback whale fetuses from the Kükenthal collection at the Museum für Naturkunde, Berlin, thus, extending historic descriptions of their skeletogenesis and providing for the first time sequences of cranial ossification for this species.
Comparative Myology and Evolution of Marsupials and Other Vertebrates, With Notes on Complexity, Bauplan, and “Scala Naturae”
TLDR
Didelphis is anatomically more plesiomorphic than are rats and humans, but its musculature is more complex than that of humans, which supports the existence of a common, easy recognizable therian Bauplan.
Development of the Ethmoid in Caluromys philander (Didelphidae, Marsupialia) With a Discussion on the Homology of the Turbinal Elements in Marsupials
TLDR
The development of the ethmoid of Caluromys philander, the bare‐tailed woolly opossum, is described based on serial sections of six pouchlings, and computed tomography images of an adult skull suggest that endoturbinal III has a developmental pattern that differs from other endoturbinals, and the name interturbinal should be retained for the adult structure.
PHYLOGENETIC TRANSFORMATIONS OF THE EAR OSSICLES IN MARSUPIAL MAMMALS, WITH SPECIAL REFERENCE TO DIPROTODONTIANS: A CHARACTER ANALYSIS
TLDR
A composite phylogeny summarizing published molecular and morphological data was used to map the characters, revealing homoplasy in all three ossicles, and the two alternative phylogenies of phalangeriforms being monophyletic or paraphyletic receive equal support from ossicle characters.
Ear ossicle morphology of the Jurassic euharamiyidan Arboroharamiya and evolution of mammalian middle ear
TLDR
The stapes and incus of the euharamiyidan Arboroharamiya from the lower Upper Jurassic of northern China are reported, which represent the earliest known mammalian middle ear ossicles and suggest development of the definitive mammalianmiddle ear (DMME), which has evolved at least three times independently in mammals.
Hand development and sequence of ossification in the forelimb of the European shrew Crocidura russula (Soricidae) and comparisons across therian mammals
Hand development in the European shrew Crocidura russula is described, based on the examination of a cleared and double‐stained ontogenetic series and histological sections of a c. 20‐day‐old embryo…
Exploring ancestral phenotypes and evolutionary development of the mammalian middle ear based on Early Cretaceous Jehol mammals
TLDR
The evolutionary changes recorded in the Mesozoic mammals are largely consistent with the middle ear morphogenesis during the ontogeny of extant mammals, supporting the relation between evolution and development.

Phylogeny and Ontogeny of Mammalian Middle Ear Structures
TLDR
Fossil finds of advanced cynodonts and early mammals demonstrate that within the synapsids a new sound transforming system evolved at the posterior angle of the mandible, which is most probably not homologous to that of sauropsids.
The phylogenetic relationships of argyrolagid marsupials
TLDR
Eleven features support the monophyly of Paucituberculata, the following three unique among Marsupialia: small size of the paraconid, procumbent second lower incisor, and supraoccipital without distinct lambdoid crest resulting in globular form of braincase.
Cranial osteogenesis in Monodelphis domestica (Didelphidae) and Macropus eugenii (Macropodidae)
TLDR
Compared data confirm suggestions that morphology at birth is conservative in marsupials and hypothesize that the pattern of cranial osteogenesis is related to two distinct demands.
New Light on the Mammalian Ear Ossicles
TLDR
The structure of the middle ear region of several therapsids is greatly illuminated by this work; but some of his conclusions seem to be open to question, while others can be further supported.
BIOLOGICAL CONSIDERATIONS OF THE MARSUPIAL‐PLACENTAL DICHOTOMY

  • Medicine
    Evolution; international journal of organic evolution
  • 1975
TLDR
The present work is a continuation with emphasis upon reproductive aspects of the problem of the marsupial-placental dichotomy in mamma lian evolution, and focuses on the condition of the newborn in the immediate common ancestor to marsupials and placentals.
Evolution of the Auditory System in Synapsida (“Mammal-Like Reptiles” and Primitive Mammals) as Seen in the Fossil Record
TLDR
The present chapter examines the extensive fossil evidence concerning the nature of the auditory machinery of early mammals and their antecedents.
Definition, diagnosis, and origin of Mammalia
TLDR
Triassic and Early Jurassic taxa commonly referred to as mammals, including Morganucodontidae, Kuehneotheriidae, and Haramiyidae, were found to lie outside of Mammalia.
The Walrus Auditory Region and the Monophyly of Pinnipeds
TLDR
The evidence supporting the traditional otariid/odobenid grouping is examined and is found to consist almost exclusively of primitive, and therefore phylogenetically uninformative, characters.
