Palaeobiogeography of Famennian (Late Devonian) bryozoans

Palaeogeography, Palaeoclimatology, Palaeoecology, 2010
Abstract Bryozoans were widely distributed in marine habitats of the Famennian (Late Devonian) worldwide. This time interval was marked by gradual change in taxonomic composition of bryozoan faunas, which were insignificantly affected by global events (Upper Kellwasser, Handerberg). Distribution of bryozoan faunas was controlled by intrinsic factors (

Western Pacific Permian marine invertebrate palaeobiogeography∗

Australian Journal of Earth Sciences, 1996
Data matrices of the presence/absence occurrence data of brachiopod genera from faunal stations throughout the western Pacific region for the Asselian‐Tastubian, Sterlitamakian‐Aktastinian, Baigendzhinian‐Early Kungurian and Kazanian‐Midian time slices of the Permian Period have been analysed by cluster analysis, non‐metric multidimensional scaling and

Early Permian (Cisuralian) global brachiopod palaeobiogeography

Gondwana Research, 2013
Abstract Palaeobiogeography of four consecutive Early Permian (Cisuralian) stages is quantitatively analyzed based on a global database of brachiopods consisting of 9131 occurrences, 3003 species of 515 genera of brachiopods from 2757 localities all over the world.

The palaeobiogeography of Permian anomodonts

Terra Nova, 1992
ABSTRACTIt is generally considered that the oldest anomodont mammal‐like reptiles are known from Late Permian sediments of the USSR and that during the rest of the Late Permian distribution of these fossils widens to encompass nearly all geographical areas by the end of the Period.This study reviews the occurrence of anomodont genera in Permian ...

hespdiv: an R package for spatially constrained, hierarchical and contiguous regionalization in palaeobiogeography

Palaeontology
The objective determination of boundaries of bioregions is a nontrivial problem. Here we present a new method family, HespDiv, and an algorithm for its implementation in a new R package: hespdiv.
