Rivista Italiana di Paleontologia e Stratigrafia, 2017 Several taxa belonging to the so called megafauna became extinct during the late Quaternary in Eurasia. The extinction chronology of the narrow-nosed rhinoceros, Stephanorhinus hemitoechus, in Europe is still uncertain and only estimated around 45 ka.

A soluble model of evolution and extinction dynamics in a rugged fitness landscape [PDF]
, 1997 We consider a continuum version of a previously introduced and numerically studied model of macroevolution (PRL 75, 2055, (1995)) in which agents evolve by an optimization process in a rugged fitness landscape and die due to their competitive ...

Climate Change and invasibility of the Antarctic benthos [PDF]
, 2007 Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli [PDF]
, 2015 The neuroanatomy of hadrosaurid dinosaurs is well known from North America and Asia. In Europe only a few cranial remains have been recovered that include the braincase. Arenysaurus is the first European endocast for which the paleoneuroanatomy has been

Scale and structure of time-averaging (age mixing) in terrestrial gastropod assemblages from Quaternary eolian deposits of the eastern Canary Islands [PDF]
, 2007 Quantitative estimates of time-averaging (age mixing) in gastropod shell accumulations from Quaternary (the late Pleistocene and Holocene) eolian deposits of Canary Islands were obtained by direct dating of individual gastropods obtained from ...
