Breaking the silence: how shedding light on the bone-skipper fly Thyreophora cynophila (Diptera: Piophilidae) demonstrated it still has a large distribution area in the Pyrenees mountains, France [PDF]
Biodiversity Data Journal, 2020 Thyreophora cynophila (Panzer, 1798) is an iconic species of the European entomofauna. This winter-flying necrophagous fly was considered long extinct in Europe, before being discovered in Spain in 2010 and re-discovered in France in 2020, with a unique locality in Saint-Paul-de-Jarrat (Ariège, southern France). After bringing this species to

The Postcranial Skeleton of an Exceptionally Complete Individual of the Plated Dinosaur Stegosaurus stenops (Dinosauria: Thyreophora) from the Upper Jurassic Morrison Formation of Wyoming, U.S.A. [PDF]
PLoS ONE, 2015 Although Stegosaurus is one of the most iconic dinosaurs, well-preserved fossils are rare and as a consequence there is still much that remains unknown about the taxon.

Skull morphology and histology indicate the presence of an unexpected buccal soft tissue structure in dinosaurs. [PDF]
J AnatA combined approach of osteology and histology was used to examine the cheek regions of dinosaurs. Strong evidence was found for a soft tissue in this region connecting the zygoma to the mandible, here named the ‘exoparia’. Abstract Unlike mammals, reptiles typically lack large muscles and ligaments that connect the zygoma to the mandible.

New perspectives on body size and shape evolution in dinosaurs. [PDF]
Biol Rev Camb Philos SocABSTRACT Diversity in the body shapes and sizes of dinosaurs was foundational to their widespread success during the Mesozoic era. The ability to quantify body size and form reliably is therefore critical to the study of dinosaur biology and evolution.

A new ankylosaurine dinosaur from the Judith River Formation of Montana, USA, based on an exceptional skeleton with soft tissue preservation [PDF]
Royal Society Open Science, 2017 The terrestrial Judith River Formation of northern Montana was deposited over an approximately 4 Myr interval during the Campanian (Late Cretaceous). Despite having been prospected and collected continuously by palaeontologists for over a century, few ...

Two new stegosaur specimens from the Upper Jurassic Morrison Formation of Montana, USA [PDF]
Acta Palaeontologica Polonica, 2019 Two partial skeletons from Montana represent the northernmost occurrences of Stegosauria within North America. One of these specimens represents the northernmost dinosaur fossil ever recovered from the Morrison Formation.

A reassessment of the purported ankylosaurian dinosaur Bienosaurus lufengensis from the Lower Lufeng Formation of Yunnan, China [PDF]
Acta Palaeontologica Polonica, 2019 The earliest definitive ornithischian dinosaurs are from the Early Jurassic and are rare components of early dinosaur faunas. The Lower Lufeng Formation (Hettangian–Sinemurian) of Yunnan Province, China, has yielded a diverse Early Jurassic terrestrial ...

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs. [PDF]
Anat Rec (Hoboken)Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.
