An 8.5 m long ammonite drag mark from the Upper Jurassic Solnhofen Lithographic Limestones, Germany

An 8.5 m long ammonite drag mark from the Upper Jurassic Solnhofen Lithographic Limestones, Germany

Trackways and tracemakers preserved together in the fossil record are rare. However, the co-occurrence of a drag mark, together with the dead animal that produced it, is exceptional. Here, we describe an 8.5 m long ammonite drag mark complete with the preserved ammonite shell (Subplanites rueppellianus) at its end. Previously recorded examples preserve ammonites with drag marks of < 1 m. The sp...

6. Upper Jurassic-lowest Cretaceous Limestones Dredged from the Western Galicia Margin

Dredge samples of Upper Jurassic-lowest Cretaceous limestones were recovered from western Galicia margin. Limestones include benthic and/or planktonic assemblages, which were deposited in environments ranging from inner to outer shelf or upper slope.

A new rhynchocephalian (Reptilia: Lepidosauria) from the Late Jurassic of Solnhofen (Germany) and the origin of the marine Pleurosauridae

A new rhynchocephalian is described based on a recently discovered and well-preserved specimen from the Late Jurassic (Kimmeridgian) marine limestones of Solnhofen, Bavaria. Phylogenetic analysis recovers the new taxon as the sister group to Pleurosauridae, a small radiation of rhynchocephalians representing the oldest marine invasion of crown-clade Lepidosauria. The relatively strong evidence ...

Diagenetic Evolution of Mudstones: Black Shales to Laminated Limestones, an Example from the Lower Jurassic of SW Britain

Morphology and ontogeny of the Upper Jurassic mantis shrimp Spinosculda ehrlichi n. gen. n. sp. from southern Germany

We describe a new species and genus of Stomatopoda (mantis shrimps), Spinosculda ehrlichi n. gen. n. sp. from the Upper Jurassic Solnhofen Lithographic Limestones of southern Germany. The species is known from two fragmentary specimens that appear to represent different ontogenetic stages. Both specimens possess a pair of posteriorly projecting movable spines dorso-laterally on the tergite of t...
