pterosaurian การใช้

It is a member of the group of pterosaurian filter-feeders.
All pterosaurian material previously assigned to this genus has been renamed " Istiodactylus ".
Even with the pterosaurian quadrupedal launching mechanism, it would have required frantic and fairly-low angled take-offs possible only in open areas, much like modern geese and swans.
In forms like " Pterodaustro ", however, which possessed long torsos and short limbs, launching might have been a more taxing and prolonged affair, only possible in large open areas, just like modern heavy-bodied aquatic birds such as swans, even with the pterosaurian quadrupedal launching.
However, in the mid-1990s, Jean-Michel Mazin and others reported that fossil footprints in Crayssac, France were similar to those reported by Stokes from the US . Mazin's tracks were more obviously pterosaurian in origin and settled the debate in favor of pterosaurs walking on all fours.
