Climate constrains the evolutionary history and biodiversity of crocodylians [PDF]
, 2015 The fossil record of crocodylians and their relatives (pseudosuchians) reveals a rich evolutionary history, prompting questions about causes of long-term decline to their present-day low biodiversity.

What, if anything, is a Paratrochamminoides? A key to the morphology of the Cretaceous to Cenozoic species of Conglophragmium and Paratrochamminoides (Foraminifera) [PDF]
, 2004 We present a review of the current taxonomical status of the genus Paratrochamminoides Soliman, 1972. We recognise five main subgroups of this genus based upon the following modes of coiling: trochospiral, streptospiral, glomospiral, triloculine or ...
