...EDWARD L. TROXELL Abstract Introduction Since beginning the study of the fossil crocodiles, about two years ago, 2 one phase of that work in particular has challenged my attention, namely, that of the mechanical structure of the bones and its bearing on the life habits of these animals. Some...

... at numerous sites of the basin ( Gasparini and Fernández, 1996 ; Spalletti et al., 1999 ). On the contrary, Middle Jurassic marine reptiles are restricted to Chacaico Sur area, southeast of the Neuquén Province ( Fig. 1 ). There, until present, ichthyosaurs, plesiosaurs, and a crocodile vertebra were found...

The evolution of extensively subdivided internal structures in the vertebrae of mamenchisaurs, diplodocids, and titanosauriforms is correlated with increasing body size and neck length and suggests that these complex morphologies were mechanically more efficient than the fossae and simple camerae of less...

Here we present for the first time a three-dimensional reconstruction of the armour plates around the tail in association with caudal vertebrae and a chevron, to give direct evidence of the body outline. The caudal vertebral column was surrounded by eight bony osteoderms, paired paramedian dorsal...
