New Papers vs. Aliens



Thanks to PM for some of these!


Carpenter, K. 2009. Role of lateral body bending in crocodylian track
making. Ichnos 16(3):202-207. doi: 10.1080/10420940802686137.

ABSTRACT: Locomotion in the alligatorids Caiman and Alligator show
ontogenetic changes in gait width, manus orientation, and the amount of
lateral body movement. In addition, the trackway of an adult Caiman is
narrower than predicted for a semierect position of the limbs based on
stance. The narrowness of the Caiman trackway is due to lateral movement of
the body during locomotion. This movement allows placement of the feet
closer to the trackway midline than would occur if no lateral bending
occurred. Lateral movement is widespread among limbed tetrapods, yet little
consideration has been given to its effects in trackmaking. Inferring stance
from fossil trackways must take into account lateral body movement,
otherwise the resultant hypothesis will be flawed.

Lots of new papers in the following volume (apparently out late last year);
I only list the dino-relevant ones, but there are others on Permian-Middle
Triassic tracks of various kinds, too:
