The fact is that at 35 feet long and five or six tons, Acrocanthosaurus was the fourth-biggest meat-eating dinosaur of the Mesozoic Era, after Spinosaurus, Giganotosaurus and Tyrannosaurus Rex (to all of which it was distantly related). Acrocanthosaurus is one of the few dinosaurs for which we know the detailed structure of its brain--thanks to an "endocast" of its skull created by computed tomography. This predator's brain was roughly S-shaped, with prominent olfactory lobes that show a highly developed sense of smell. Intriguingly, the orientation of this theropod's semicircular canals (the organs in the inner ears responsible for balance) implies that it tilted its head a full 25 percent below the horizontal position. Acrocanthosaurus is a genus of carcharodontosaurid dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous, from 113 to 110 million years ago. Acrocanthosaurus was a bipendal predator. As the name suggests, it is best known for the high neural spines on many of its vertebrae, which most likely supported a ridge of muscle over the animal's neck, back, and hips. Acrpcanthosaurus was one of the largest theropods, with the largest known specimen reaching 11–11.5 meters (36–38 ft) in length and weighing approximately 4.4–6.6 metric tons (4.9–7.3 short tons). Acrocanthosaurus was the largest theropod in its ecosystem and likely an apex predator that preyed on sauropods, ornithopods, and ankylosaurs.
We make no representations as to the accuracy of the figures attached to the Geocache. Obviously dinosaurs have been extinct for millions of years and the descriptions included are based upon research of paleontologists and other scientists much more learned than El Fartero & La Vaca Verde.
"Walking with Dinosaurs" is a Reptilia-themed power trail consisting of 25 traditonal microcaches hosting their featured dinosaur, and 2 large, well-stocked ammocans you'll have to answer some questions to find. It extends for a total of 4 miles north from Hubbel Corners toward Grand Gorge on the lovely, but lesser known Southern portion of the Stamford Rail Trail. The trail is mostly flat, wide and level, and other than a few sections that can get watery, it is dog, stroller and bike friendly. Most of the caches are winter-friendly, but a few are not, so check the attributes if there's deep snow. We recommend doing it over two days for a more enjoyable, leisurly experience, but more ambitious cachers (or First-to-Find maniacs!) can start early and do it in one. We have tried to provide good coordinates and helpful hints to give you a rewarding caching experience.
Parking is available at the South end of the trail at N42 18.165 W74 33.256, or at the North end at N42 21.238 W74 31.250
