The Early Evolutionary History of Belemnites: New Data from Japan
Belemnites (Order Belemnitida), a very successful group of Mesozoic coleoid cephalopods, dominated the world's oceans throughout the Jurassic and Cretaceous. According to the current view, the phylogenetically earliest belemnites are known from the lowermost Jurassic (Hettangian, 201-199 Ma) of northern Europe. They are of low diversity and have small sized rostra without clear grooves. Their d...

متن کاملNon-invasive diagnostics in fossils - Magnetic Resonance Imaging of pathological belemnites
For more than a decade, Magnetic Resonance Imaging (MRI) has been routinely employed in clinical diagnostics because it allows non-invasive studies of anatomical structures and physiological processes in vivo and to differentiate between healthy and pathological states, particularly of soft tissue. Here, we demonstrate that MRI can likewise be applied to fossilized biological samples and help i...

متن کاملThe first definite record of a Valanginian ichthyosaur and its implications on the evolution of post-Liassic Ichthyosauria
A complete ichthyosaur rostrum, with 124 associated teeth, was recently discovered in Laux-Montaux locality, department of Drôme, southeastern France. The associated belemnites and ammonites indicate a late Valanginian age (Neocomites peregrinus Zone, Olcostephanus nicklesi Subzone) for this fossil, which consequently represents the first diagnostic ichthyosaur ever reported from Valanginian st...
