Just out @ Neues Jahrbuch für Geologie und Paläontologie – Abhandlungen Aalenian-Bajocian belemnites from the Middle and High Atlas, Morocco: taxonomy, biostratigraphy and palaeobiogeographical affinities Author(s) Weis, Robert; Sadki, Driss; Mariotti, Nino Abstract: The early Middle Jurassic represents an interval of important taxonomic diversification in belemnites in the Western Tethys. Field work in the Moroccan Atlas mountains has permitted to collect numerous belemnite rostra, ranging from the uppermost Aalenian (Concavum Zone) to

On the News @ The Guardian Title:  Pincer-wielding 507m-year-old fossil sheds light on evolution of crabs Excerpt: “A fossilised ancient creature boasting huge pincers resembling can-openers, a hinged two-piece shell and more than 50 pairs of legs has been discovered, shedding light on the evolutionary past of a huge and diverse group of animals. Researchers say the creature, thought to have lived about 507 million years ago during the Cambrian

Just out @ Nature Burgess Shale fossils illustrate the origin of the mandibulate body plan Author(s) Cédric Aria & Jean-Bernard Caron Abstract: Retracing the evolutionary history of arthropods has been one of the greatest challenges in biology. During the past decade, phylogenetic analyses of morphological and molecular data have coalesced towards the conclusion that Mandibulata, the most diverse and abundant group of animals, is a distinct clade from Chelicerata, in that its

Perkovsky Abstract: Glaesoconis popovi sp. nov. (Neuroptera: Coniopterygidae) is described from Upper Cretaceous (Santonian) Taimyr amber of northern Siberia (Yantardakh locality). The new species may be distinguished from others in the genus by much smaller eyes and the shape of the terminal segment of the maxillary palpus.
