Recent discoveries in Asia have greatly increased our understanding of the evolution of dinosaurs' integumentary structures, revealing a previously unexpected diversity of "protofeathers" and feathers. However, all theropod dinosaurs with preserved feathers reported so far are coelurosaurs. Evidence for filaments or feathers in noncoelurosaurian theropods is circumstantial and debated. Here we report an exceptionally preserved skeleton of a juvenile megalosauroid, Sciurumimus albersdoerferi n. gen., n. sp., from the Late Jurassic of Germany, which preserves a filamentous plumage at the tail base and on parts of the body. These structures are identical to the type 1 feathers that have been reported in some ornithischians, the basal tyrannosaur Dilong, the basal therizinosauroid Beipiaosaurus, and, probably, in the basal coelurosaur Sinosauropteryx. Sciurumimus albersdoerferi represents the phylogenetically most basal theropod that preserves direct evidence for feathers and helps close the gap between feathers reported in coelurosaurian theropods and filaments in ornithischian dinosaurs, further supporting the homology of these structures. The specimen of Sciurumimus is the most complete megalosauroid yet discovered and helps clarify significant anatomical details of this important basal theropod clade, such as the complete absence of the fourth digit of the manus. The dentition of this probably earlyposthatchling individual is markedly similar to that of basal coelurosaurian theropods, indicating that coelurosaur occurrences based on isolated teeth should be used with caution.feather evolution | Megalosauridae | Theropoda | Upper Jurassic

“…While both true feathers and assorted types of integument have been reliably documented in numerous small sized coelurosaurians, such structures remain elusive for larger animals with only a series of long quill-like fibres described for the midsized 2.2 m long therizinosauroid theropod B. inexpectus (Xu et al 1999a). A recent example of this complexity was the controversy surrounding the small dinosaur Juravenator starki, which was assigned to the Compsognathidae (Göhlich and Chiappe 2006). Other members of this family include Sinosauropteryx for which filament-like structures are well known; however, Juravenator was found with a patch of skin on the tail which is scaled with no sign of feathers, not even impressions of follicles that might indicate the loss of the same (Göhlich and Chiappe 2006;Xu 2006).…”

“…Indeed, most specimens are in excellent state of preservation and some of them also have soft tissues, feathers and/or gut contents preserved (Ostrom 1978, Norman 1990, Chen et al 1998, dal Sasso and Signore 1998, Naish et al 2004, Göhlich and Chiappe 2006, Ji et al 2007, Chiappe and Göhlich 2010. If this hypothesis is correct two implications are plausible (see below).…”

“…1a). Juravenator starki Göhlich and Chiappe 2006 is also from Germany, but it was found in the Schamhaupten plattenkalk, which is at least five million years older than Solnhofen Chiappe 2006, Chiappe andGöhlich 2010). In this way the two species were not coeval.…”

The paleobiogeography of the theropod clade Compsognathidae is here reaccessed in order to test the hypothesis of this taxon being adapted specifically to inhabit semi-arid environments. Data about localities where these fossils were collected and their paleoenvironments were gathered from the literature. Compsognathids seem to be found especially in sedimentary deposits known as Fossil Lagerstätten, which were formed under a set of specific conditions that allowed the preservation of the fragile bone remains of these animals. This bias limits an accurate analysis of the historical and/or ecological paleobiogeography of this taxon. Actually, it is possible that compsognathids had an almost worldwide distribution during the Mesozoic Era. Their occurrence in Lower Cretaceous rocks of China suggests that they also inhabited environments with moist conditions instead of being restricted to semi-arid to arid environments.
