Jurellana tithonia n. sp. is the earliest known Porcellanidae, from the Tithonian Ernstbrunn Limestone, Austria. Porcellanids are well-known from the fossil record, already having been described from Cretaceous, Eocene, and Neogene rocks. Their occurrence in the Jurassic is not surprising, because the Infraorder Anomura, to which they belong, is the ...

Zapaliinae, a new subfamily of Tithonian–Berriasian ataxioceratid ammonites

PalZ, 2017
The recent recognition of the earliest Andean Tithonian ammonite fauna (Picunleufuense Zone) has allowed a balanced classification of the ataxioceratid ammonites, reflecting their phylogenetic relationships. The Picunleufuense Zone fauna, first recognized in the Neuquen Basin at the base of the Vaca Muerta Formation, is represented by numerous records ...
