First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

The Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...
