... with buried nests and precocial young. Here we taphonomically describe nesting sites of two crocodylians, American crocodile ( Crocodylus acutus ) at Turkey Point, Florida and broad-snouted caiman ( Caiman latirostris ) from Santa Fe and Chaco provinces, Argentina. Surveys focused on eggshell abundance...

..., especially among caimans, but some range extensions necessary to improve consistency are unreasonably long. Quartet dating appears to systematically undercompensate branch length error with late calibrations and overcompensate it with early calibrations, but in all cases very reasonable results—alligatorid...

... on the manus (all pterosaurs have four); and 2, pterosaurs did not walk quadrupedally. However, trackways similar in detail to the poorly preserved Pteraichnus can be simulated experimentally by a small caiman, and we suggest that Pteraichnus could have been made by a crocodilian. Experimental work...
