Neuroanatomy of the spinosaurid Irritator challengeri (Dinosauria: Theropoda) indicates potential adaptations for piscivory

Schade, Marco ; Rauhut, Oliver W. M. ; Evers, Serjoscha W.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 9259

Spinosauridae, a theropod group characterized by elongated snouts, conical teeth, enlarged forelimbs, and often elongated neural spines, show evidence for semiaquatic adaptations and piscivory. It is currently debated if these animals represent terrestrial carnivores with adaptations for a piscivorous diet, or if they largely lived and foraged in aquatic habitats. The holotype of Irritator...

Birds have peramorphic skulls, too: anatomical network analyses reveal oppositional heterochronies in avian skull evolution

Plateau, Olivia ; Foth, Christian

In: Communications Biology, 2020, vol. 3, no. 1, p. 195

In contrast to the vast majority of reptiles, the skulls of adult crown birds are characterized by a high degree of integration due to bone fusion, e.g., an ontogenetic event generating a net reduction in the number of bones. To understand this process in an evolutionary context, we investigate postnatal ontogenetic changes in the skulls of crown bird and non-avian theropods using anatomical...

A detailed review on the clinical anatomy of the pectoralis major muscle

Larionov, Alexey ; Yotovski, Peter ; Filgueira, Luis

In: SM Journal of Clinical Anatomy, 2018, vol. 2, no. 3, p. 1015

The pectoralis major is a muscle of the upper limb girdle. This muscle has a unique morphological architectonic and a high rate of clinical applications. However, there is lack of data regarding the morphological and functional interactions of the pectoralis major with other muscle and fascial compartments. According to the applied knowledge, the “Humero-pectoral” morpho-functional...

The oldest Archaeopteryx (Theropoda: Avialiae): a new specimen from the Kimmeridgian/Tithonian boundary of Schamhaupten, Bavaria

Rauhut​, Oliver W.M. ; Foth, Christian ; Tischlinger, Helmut

In: PeerJ, 2018, vol. 6, p. e4191

The iconic primeval bird Archaeopteryx was so far mainly known from the Altmühltal Formation (early Tithonian) of Bavaria, southern Germany, with one specimen having been found in the overlying Mörnsheim Formation. A new specimen (the 12th skeletal specimen) from the earliest Tithonian Painten Formation of Schamhaupten (Bavaria) represents the so far oldest representative of the genus. The...

Key features of mcr-1-bearing plasmids from Escherichia coli isolated from humans and food

Zurfluh, Katrin ; Nüesch-Inderbinen, Magdalena ; Klumpp, Jochen ; Poirel, Laurent ; Nordmann, Patrice ; Stephan, Roger

In: Antimicrobial Resistance & Infection Control, 2017, vol. 6, p. 91

Mcr-1-harboring Enterobacteriaceae are reported worldwide since their first discovery in 2015. However, a limited number of studies are available that compared full-length plasmid sequences of human and animal origins.

The last European varanid: demise and extinction of monitor lizards (Squamata, Varanidae) from Europe

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Journal of Vertebrate Paleontology, 2017, vol. 37, no. 2, p. e1301946

Remains of a varanid lizard from the middle Pleistocene of the Tourkobounia 5 locality near Athens, Greece are described. The new material comprises cranial elements only (one maxilla, one dentary, and one tooth) and is attributed to Varanus, the genus to which all European Neogene varanid occurrences have been assigned. Previously, the youngest undisputed varanid from Europe had been...
