Parabrontopodus
Parabrontopodus is an ichnogenus of dinosaur footprint, that was initially described by Lockley et al. in 1994, and was assigned to Sauropoda by Lockley in 2002 and in 2004 by Niedzwiedzki and Pienkowski. Various species through their footprints that are characterized by the association of two impressions left by hand and foot. The acquisition of a specific family is complex, but now in most cases, they have been considered diplodocoids and similar animals. The reason is that their traces left are large, but in proportion to the size, from animals, seem very light because the depth of imprint is low.
Farlow, in 1992, had given a criterion for classifying sauropod tracks. Traces are distinguished wide as Brontopodus and the narrow track related to Breviparopus. As the Parabrontopodus track ratio is 1:5, it is considered narrow by Lockley.
Species recognized
- P. mcintoshi - It was built on the basis of abundant fossil tracks at the Purgatoire site southeast of Colorado, but the holotype is a pair of hands and feet. The footprint measures. The type species is considered a diplodocoid.
- P. distercii - Based on a trackway consisting of 17 prints of the fore and hind feet found at the site of Salgar Chairs. The hind footprints are elongated, averaging long and only wide.
