Palaeobiogeography of Mesozoic Mammals – Revisited
2012The fossil record of mammals in the Mesozoic is decidedly meagre in comparison to that of the Cainozoic, but some useful generalisations can be drawn about the biogeographic history of this group during the Mesozoic. Compared with the Jurassic, when cosmopolitanism was frequent among the mammalian families, regionalism became more pronounced in the ...

Evolution, palaeobiogeography and palaeoecology of Eucommiaceae
Journal of Palaeosciences, 2000A comprehensive treatise incorporating morphology, ecology, stratigraphy and systematics of Eucommia belonging to family Eucommiaceae, based on extant and extinct records, is presented. Fifteen species of megafossil leaves and fruits of Eucommia and about one hundred localities from the northern hemisphere are known. Pollen of Eucommiidites troedssonii

Chapter 14 Palaeobiogeography of Ordovician echinoderms
Geological Society, London, Memoirs, 2013AbstractThe palaeobiogeographical distribution of the six major clades of Ordovician echinoderms (asterozoans, blastozoans, crinoids, echinozoans, edrioasteroids and stylophorans) is analysed based on a comprehensive and up-to-date database compiling 3701 occurrences (1938 species recorded from 331 localities) of both complete specimens and isolated ...

Evolution, palaeobiogeography, and life history
1996Abstract One step further from reality, we enter here the realm of evolutionary processes and life history, i.e. all the flesh that one may put on fossils, homologies, and phylogenetic patterns: whence, how, and why early vertebrates evolved, how they lived, on what they preyed, etc.

Palaeobiogeography of the Early Cretaceous corals
Palaeogeography, Palaeoclimatology, Palaeoecology, 1992Abstract A compilation of the geographical distribution of about 1000 species of corals from the Early Cretaceous (Valanginian to Cenomanian) is presented. After the reefal regression during the latest Jurassic, no corals appear in the Berriasian, and only a few species are known from the Valanginian and Hauterivian.

Early Palaeozoic palaeobiogeography and palaeoecology of stylophoran echinoderms
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Abstract Stylophorans (cornutes, mitrates) represent one of the most diverse classes of Cambro-Ordovician echinoderms. They were free-living, benthic, non-radiate forms, closely related to asterozoans and crinoids. Taphonomic, sedimentological, and palaeosynecological data provide useful information on key aspects of stylophoran palaeoecology. Such a

The Palaeobiogeography of the Blastoidea (Echinodermata)
Geological Society, London, Memoirs, 1990Abstract The 100 blastoid genera are known from some 1500 localities on every continent except Antarctica. Although fissiculates were more geographically widespread than spiraculates, the spiraculates tended to dominate most faunas numerically. The typical blastoid genus is monospecific, relatively short lived (range limited to some part of a
