Are monotremes primitive and marsupials inferior?

, 2015
This chapter deals with some of the many prejudices surrounding the value of marsupials and monotremes as research organisms. It shows that most published research on mammalian biology actually only deals with placentals, and explains the historical ...

Skull Morphological Evolution in Faunivorous Marsupials [PDF]

Marsupials have a long evolutionary history of diversification in the Southern Hemisphere, where they expanded geographic distribution from America through Antarctica, reaching Australasia.

Secondary cartilage in the murine medial pterygoid plate has a critical role in the pathfinding of the tensor veli palatini

Journal of Anatomy, EarlyView.
The development of the medial pterygoid plate (MPP) is followed in mouse embryos, highlighting its neural crest origin and complex development via both endochondral and membranous ossification. Using transgenic mice, the secondary cartilage of the MPP is shown to direct the path of the tensor veli palatini.

Therian origin of INSL3/RXFP2-driven testicular descent in mammals

Frontiers in Cell and Developmental Biology
Introduction: During early development in most male mammals the testes move from a position near the kidneys through the abdomen to eventually reside in the scrotum.

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

Journal of Anatomy, EarlyView.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

The variability of giraffe skull morphology

Journal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

Torpor in marsupials: recent advances

, 2012
We report new findings about torpor in marsupials with regard to three energy-demanding processes: (i) development and growth, (ii) reproduction, and (iii) rewarming.

Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods

Journal of Anatomy, EarlyView.
Manual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.

The evolution of the Australian marsupials.

, 1976
Tne oldest marsupial fossils have been found in North America and the marsupials are thought to have originated there in the early Cretaceous. The marsupial eutherian ancestor could have had either a marsupial type of viviparity or may have been ...
