Mammal Teeth from the Forest Marble (Middle Jurassic) of Oxfordshire, England

Abstract

A very early stage in the evolution of the talonid basin is seen in a eupantothere lower molar from the Upper Bathonian of central England. The corresponding upper molars and the first known Middle Jurassic morganucodontid, kuehneotheriid, and dryolestid teeth are briefly described and illustrated.

Mammals from the Late Jurassic Qigu Formation in the Southern Junggar Basin, Xinjiang, Northwest China

“…The Liuhuanggou mammal assemblage also shares similarities with the wellknown Bathonian Forest Marble assemblage of England (Butler and Hooker 2005;Freeman 1976Freeman , 1979Kermack et al 1987Kermack et al , 1998Kielan-Jaworowska et al 2004;Martin and Averianov 2010;Sigogneau-Russell 1998, 2003a. Both assemblages share eleutherodontid allotherians, simpsonodontid, and tegotheriid docodontans, and stem-lineage zatherians.…”

Relationships of the dog‐like marsupials, deltatheroidans and early tribosphenic mammals

“…Aegialodontia in turn may have originated from more primitive Peramura that had four molars. A possible candidate is Palaeoxonodon from the Bathonian (Middle Jurassic, about 170 Ma) of England (Freeman 1976). The dental formula of Palueo.vorzodon is not known, but its lower molar has a well-developed trigonid and a small lingually placed talonid that suggest aegialodontian affinity.…”

The dentary of Wareolestes rex (Megazostrodontidae): a new specimen from Scotland and implications for morganucodontan tooth replacement

“…Wareolestes rex was erected as a new genus and species by Freeman () for a single well preserved molar tooth discovered at Kirtlington cement quarry, an exposure of the Middle Jurassic Forest Marble Formation in Oxfordshire, UK, which has yielded multiple representatives of early mammaliaform groups (Freeman , ; Kermack et al . ; Sigogneau‐Russell , ; Butler & Hooker ).…”
