Psammoecus delicatus Grouvelle 1908

based on its type material and a revised key to identify species in the genus are also provided. A phylogenetic analysis based upon four genes (COI, 16S, 18S, 28S) confirms its position within Hesionini.

Consistent drivers of coastal biodiversity across the tree of life

Coastal ecosystems are threatened by global change but remain understudied despite their importance for biodiversity and human society. For instance, most coastal studies and monitoring programs focus on a few groups of organisms owing to methodological limitations. However, high...

Cuticular surface microstructure in Chelodesmidae and some related families (Diplopoda: Polydesmida)

Summary. The cuticular surface structures of 23 species of the family Chelodesmidae, as well as 11 species of related families, were studied using a scanning electron microscope. Cytoscute shapes were found to vary, from a regular penta-/hexagonal shape to a stretched and/or bran...

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena...

Coprolites from the Earliest Eocene Sundby Bed, Mors, Denmark and the Record of Marine Vertebrate Coprolites Across the Cretaceous/Paleogene Boundary

In total, 1000+ specimens of coprolites have been collected from the Eocene Sundby bed, which marks the top of the Stolleklint Clay of the Ølst Formation at the locality Sundby Klint East on the island Mors in northern Jylland, Denmark. The coprolites contain seven distinct morph...

The chemical composition of narwhal tusk and tooth is impacted by geographical locality

Abstract The possible relationship between diet and geographical locality is important for understanding the putative effects of climate change on animal behaviour and survival. Narwhals have two maxillary teeth, one of which may become a tusk. In these teeth, various chemical el...
