Forni Dolostone
The Forni Dolostone, also known as the Dolomia di Forni, is a Late Triassic (Norian, or Alaunian in the local biochronology) dolomite geological formation in northeastern Italy. The formation was deposited in a lagoonal to shallow marine environment.Dolomia di Forni at .org Description It represents deposition in an anoxic marine basin whose maximum depth was about , and was surrounded by the shallow water carbonate platform of the Dolomia Principale Formation. The Dolomia di Forni is co ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoracopterus
''Thoracopterus'' is an extinct genus of overwater gliding ray-finned fish. It was common to the late Middle Triassic and Late Triassic epochs in what is now Europe and China. ''Thoracopterus'' had elongate pectoral fins, similar to modern Exocoetidae, which are used to glide overwater in order to escape aquatic predators. ''Thoracopterus'' represents the earliest known example for overwater gliding in actinopterygians. References * Fishes of the World ''Fishes of the World'' by the American ichthyologist Joseph S.

Pseudodalatias
''Pseudodalatias'' is an extinct genus of squaliform shark which existed in England, Italy and Spain during the Triassic period.

Drepanosaurus
''Drepanosaurus'' (; "sickle lizard") is a genus of arboreal (tree-dwelling) reptile that lived during the Triassic Period. It is a member of the Drepanosauridae, a group of diapsid reptiles known for their prehensile tails. ''Drepanosaurus'' was probably an insectivore, and lived in a coastal environment in what is now modern day Italy, as well as in a streamside environment in the midwestern United States. Description ''Drepanosaurus'' is known to have a huge claw on the "index finger" (digit II) of each hand along with the tail claw. The skull of ''Drepanosaurus'' has never been found and is still unknown; however, the skull of ''Drepanosaurus'' was likely similar to other drepanosaurs, such as ''Megalancosaurus''. ''Megalancosaurus skull was approximately the same size as its enlarged claws, and had a bird-like jaw and head shape. The forelimb of ''Drepanosaurus'' is highly modified compared to other vertebrates. Its ulna was modified into a robust, crescent-shaped site fo ...

Megalancosaurus
''Megalancosaurus'' is a genus of extinct reptile from the Late Triassic Dolomia di Forni Formation and Zorzino Limestone of northern Italy, and one of the best known drepanosaurids. The type species is ''M. preonensis''; a translation of the animal's scientific name would be "long armed reptile from the Preone Valley." Anatomy ''Megalancosaurus'' was fairly small, its adult length was only about 25 centimeters (10 inches). It was built like a chameleon and probably lived a similar arboreal lifestyle, feeding on insects and other small animals. Even its feet were chameleon like, with two toes being opposed to the remaining three. The tail is long, prehensile, and bears a strange claw-like organ made of fused vertebrae at its end. Its shoulders formed a withers that would have served as an attachment site for especially strong muscles. Some specimens have an opposable digit on the feet. Because not all members of the species appear to bear this digit, it has been speculated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langobardisaurus
''Langobardisaurus'' (, meaning Reptile of Langobardi, in reference to the Long Bearded People, an ancient Italian civilization) is an extinct genus of tanystropheid archosauromorph reptile, with one known species, ''L. pandolfii''. Its fossils have been found in Italy and Austria, and it lived during the Late Triassic period, roughly 228 to 201 million years ago. The ''Langobardisaurus'' was first discovered by Italian paleontologist Silvio Renesto in 1994 from the Calcare di Zorzino Formation in Northern Italy. Description Neck and skull The ''Langobardisaurus'' was a small reptile with a body size shorter than 50 cm. Despite its small size, the ''Langobardisaurus'' featured a long neck with elongate cervical vertebrae featuring low neural spines. Atop its long neck, the ''Langobardisaurus'' had a large yet short triangular skull that featured a small rostrum and large orbits. Its large orbits are evidence of reliance on visual perception – this suggests that the ''La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudimorphodon
''Eudimorphodon'' was a pterosaur that was discovered in 1973 by Mario Pandolfi in the town of Cene, Italy and described the same year by Rocco Zambelli. The nearly complete skeleton was retrieved from shale deposited during the Late Triassic (mid to late Norian stage),Wellnhofer, P. (1991). "Summary of Triassic Pterosaurs." ''The Illustrated Encyclopedia of Pterosaurs.'' London, UK: Salamander Books Limited. p. 67. . making ''Eudimorphodon'' one of the oldest pterosaurs known.Cranfield, I. ''The Illustrated Directory of Dinosaurs and Other Prehistoric Creatures''. London: Salamander Books, Ltd. Pp. 280–281. It had a wingspan of about and at the end of its long bony tail may have been a diamond-shaped flap like in the later ''Rhamphorhynchus''. If so, the flap may have helped it steer while maneuvering in the air. ''Eudimorphodon'' is known from several skeletons, including juvenile specimens. Discovery and species ''Eudimorphodon'' currently includes one species, the type sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seazzadactylus Skull
''Seazzadactylus'' is a basal pterosaur genus that during the late Triassic lived in the area of present Italy. Discovery In 1997, amateur paleontologist Umberto Venier discovered the skeleton of a pterosaur in a boulder laying in the bed of the Seazza brook, just before it joins the Tagliamento river, near Preone in the Dolomites. Venier brought the find to the '' Museo Friulano di Storia Naturale'' at Udine. After partial preparation paleontologist Fabio Marco Dalla Vecchia announced the discovery in the scientific literature in 2000. In 2003, Dalla Vecchia referred the specimen to '' Eudimorphodon''. In 2009 however, further preparation made him conclude that it was a species new to science, not identical to either ''Eudimorphodon'' or '' Carniadactylus''. In 2019, Dalla Vecchia named and described the type species ''Seazzadactylus venieri''. The generic name combines that of the Seazza with the Greek , 'finger'. The specific name honours Venier as discoverer. The holotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
