Trex vision as support for scavenging... If my figures are
correct-- Taking a Trex stride as 1.76m, assuming a stride
frequency of 2 seconds (I believe 2 sec is conservative), and
using Stevens' far point of 6 km, Trex could walk to his
limiting far point in ~1.9 hrs. This means that, assuming visual
cues in the form of volant scavengers were available, Trex could
monitor, from a stationary position, ~113 sq km (11340 hectares)
with a two hour arrival time. Traversing a regular circuit, or
moving with a herd of prey animals, could obviously enlarge this
area several fold. This appears to mean that the hypothesis that
Trex obtained a significant portion of its diet from fortuitous
death is more likely (ie, not as ridiculous) as I once thought
it to be-- ASSUMING THAT VISUAL CUES (EG, VOLANT SCAVANGERS)
WERE "AVAILABLE".
