FIRST RECORD OF ICHTHYOSAURS IN SICILY(UPPER TRIASSIC OF MONTE SCALPELLO, CATANIA PROVINCE)
Rivista Italiana di Paleontologia e Stratigrafia, 2014 Here we report for the first time on the presence of ichthyosaurs in Sicily, southern Italy. The deposit of origin (Mufara Formation) can be dated to the upper Carnian (Tuvalian substage) based on a typical association of ammonites, one of which ...

Skeletal completeness of the non‐avian theropod dinosaur fossil record
Palaeontology, Volume 62, Issue 6, Page 951-981, November 2019., 2019 Abstract Non‐avian theropods were a highly successful clade of bipedal, predominantly carnivorous, dinosaurs. Their diversity and macroevolutionary patterns have been the subject of many studies. Changes in fossil specimen completeness through time and space can bias our understanding of macroevolution.

The fossil record of ichthyosaurs, completeness metrics and sampling biases
Palaeontology, Volume 58, Issue 3, Page 521-536, May 2015., 2015 Abstract Ichthyosaurs were highly successful marine reptiles with an abundant and well‐studied fossil record. However, their occurrences through geological time and space are sporadic, and it is important to understand whether times of apparent species richness and rarity are real or the result of sampling bias.

III. On the shoulder girdle in ichthyosauria and sauropterygia [PDF]
Proceedings of the Royal Society of London, 1892 Abstract The author discusses the structure of the shoulder girdle and the homologies of its several parts in these families. He shows that the alleged existence of a precoracoid in the Ichthyosauria rests on an insufficient foundation; offers proofs that in Plesiosauria the anterior ventral ray is not only theoretically but actually ...
