Body-size reduction is considered an important response to current climate warming and
has been observed during past biotic crises, including the Pliensbachian–Toarcian crisis, a …

A remarkable specimen of the actinopterygian fish Pachycormus macropterus from the Early
Jurassic (Toarcian) Posidonienschiefer Formation of Germany exceptionally preserves an …

Although belemnites form a major clade of extinct cephalopods, the early stage of their
diversification remains poorly known in time and space. Here we investigate the first …

In the Amellago area (central High Atlas), the widely distributed Toarcian succession
consists of marls and marly limestones of the Tagoudite and Agoudim formations. We here …

The uppermost lower Toarcian and middle Toarcian succession of the Central Unit of the
South Riffian Ridges, particularly in the El Heitouf and Sned sections, is rich in benthic …

Multiple approaches, mainly focused on assessing the depositional environments,
paleotemperature, chronostratigraphical and paleobiogeographical data, morphometrical …

Abstract The second-order Pliensbachian–Toarcian crisis affected major groups of marine
organisms. While its impact has been intensively studied for ammonites, the response of …

Many localities worldwide yielded rich Toarcian (Early Jurassic) ammonoid faunas whose
diversity history enhanced our understanding of global events and their geographic …

Ammonite phylogeny has mainly been established based on a stratigraphic approach, with
cladistics underconsidered. The main arguments against the use of cladistics are the …

High‐resolution analysis of the late Pliensbachian–early Toarcian belemnite assemblages
from the Peniche section (Lusitanian Basin) has enabled, for the first time, recognition of …
