On the Structure of the Plesiosauria Skull [PDF]
The structure of the skull of the Liassic Plesiosauria has been discussed by many writers, but the various accounts that have been given of it are incomplete, and often differ one from the other in important particulars, doubtless owing to the fact that in most cases the specimens examined are much crushed, and are embedded in the matrix ...

On the cranial anatomy of the polycotylid plesiosaurs, including new material of Polycotylus latipinnis, Cope, from Alabama [PDF]
The cranial anatomy of plesiosaurs in the family Polycotylidae (Reptilia: Sauropterygia) has received renewed attention recently because various skull characters are thought to indicate plesiosauroid, rather than pliosauroid, affinities for this family ...

Skeletal completeness of the non‐avian theropod dinosaur fossil record
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.
