Tooth Replacement in Late Jurassic Dryolestidae (Eupantotheria, Mammalia)

Journal of Mammalian Evolution, 1997
The discovery of juvenile dentitions of late Jurassic (Kimmeridgian) Dryolestidae (Eupantotheria, Mammalia) from Guimarota, Portugal, yields for the first time information on the mode of tooth replacement in therian mammals prior to the dichotomy of placentals and marsupials. As in extant placentals, tooth replacement occurs at all antemolar positions [

The ossification does not involve the intervertebral space or the annulus fibrosus of the disc and therefore represents true bridging.

Middle and Late Jurassic terebratulides from New Zealand

Palaeoworld, 2016
Abstract Terebratulide brachiopods are found throughout the New Zealand Mesozoic, and by the Jurassic are second only to rhynchonellides in abundance and diversity. Only two species have been described from the Late Jurassic, Kutchithyris hendersoni Marwick, 1953 and Holcothyris (?) kaiwaraensis Campbell, 1965 . In this study, one new genus and 14

Late Jurassic Mammals from Tendaguru, Tanzania, East Africa

Journal of Mammalian Evolution, 1998
Records of Mesozoic mammals are extremely rare in Africa. The only previous record from the Upper Jurassic of Africa is a fragmentary mandible without teeth of Brancatherulum tendagurense. Here I report the discovery of two new mammals from the Upper Jurassic of Tendaguru, Tanzania.

Characteristics of Yichun Late Triassic - Early Jurassic Monzogranite

Applied Mechanics and Materials, 2011
As building material, Granite has been extensively used. It is important to clear the geochemical characteristics of granites. The paper introduce the Late Triassic-Early Jurassic monzogranite, it mainly located in the south of Yichun area, which were intruded by medium grain monzogranite and syenogranite in Late Triassic-Early Jurassic.
