Acrocanthosaurus
Click here for more Acrocanthosaurus Pictures
Acrocanthosaurus was a common carnivorous (meat-eating) dinosaur
in North America during the mid
Cretaceous period,
between approximately 125 and 100 million
years ago. It lived in North America -
fossils of the animal have been
mainly found in the US states of Oklahoma and Texas, but fossilized teeth have been found as far East as Maryland.
Acrocanthosaurus was up to 40 feet (12 meters) long,
and weighed approximately 2.4 tons.
One usual feature of Acrocanthosaurus is the large neural spines on the
vertebrae of the neck, back, hips and upper tail.
It is not thought that it had a sail on its back like
Spinosaurus (which was unrelated, and had
much larger neural spines), but rather it is thought the spines had
attachments for powerful muscles, similar to those found in modern bison.
Its not entirely clear what the purpose of these spines and muscles were
- possibilities include fat storage, communication, or temperature regulation.
Acrocanthosaurus was a carnivore, but is not believed to have been a fast runner.
Its forelimbs and shoulders are also unusual, and seem to have been very strong,
had lots of cartilage, but been quite stiff with very limited movement.
It is thought that the forelimbs hung down and inwards, and would not have been
used for seizing prey. Acrocanthosaurus may instead have seized prey with its
jaws, and used its forelimbs to prevent the prey escaping. It is also possible
that Acrocanthosaurus may have held the prey in its jaws, and used the claws in
its forelimbs to tear gashes into the prey.

Click Here | - Provides updated detail on the latest theories about the the dinosaur extinction
Product Description:
In the spring of 1983 amateur paleontologist Cephis Hall dug up a massive femur bone from a waste holding pit near the edge of the Mountain Fork River on land owned by a powerful multi-national corporation. The discovery intrigued and impelled him on an epic quest to excavate and recover a world-class dinosaur specimen, but indomitable people and institutions stood in his way. The pursuit of his dream sent him on an arduous journey and collision course against mighty foes. Cephis and his partner, Sid Love, never imagined the ensuing struggles and unfolding consequences they would ultimately face. The real story and struggle began after the dinosaur was removed from the pit. The author has blended science, history, politics, and controversy into an amazing and heroic account of two men's real life adventures and impossible struggles against overwhelming odds. Their story represents one of the greatest achievements of paleontological history. This book contains some of the latest and most provocative research and theory regarding the controversy over the dinosaur extinction of the late Cretaceous (65 million years ago). The most amazing thing about their story is that it is true. If you favor the underdog, you should buy this book. |

The meat-eating dinosaurs, or Theropoda, include some of the fiercest predators that ever lived. Some of the group's members survive to this day—as birds. The theropod/bird connection has been explored in several recent works, but this book presents 17 papers on a variety of other topics. It is organized into three parts. Part I explores morphological details that are important for understanding theropod systematics. Part II focuses on specific regions of theropod anatomy and biomechanics. Part III examines various lines of evidence that reveal something about theropods as living creatures. The contributors are Ronan Allain, Rinchen Barsbold, Kenneth Carpenter, Karen Cloward, Rodolfo A. Coria, Philip J. Currie, Peter M. Galton, Robert Gay, Donald M. Henderson, Dong Huang, James I. Kirkland, Yoshitsugu Kobayashi, Eva B. Koppelhus, Peter Larson, Junchang Lü, Lorrie A. McWhinney, Clifford Miles, Ralph E. Molnar, N. Murphy, John H. Ostrom, Gregory S. Paul, Licheng Qiu,J.

Click Here | Product Description:
On a muddy riverbank, a hungry dinosaur stalks her prey. From her hiding place in the nearby trees, she spies a giant, four-legged plant eater. At the right moment, she leaps from the trees and lunges at the slower dinosaur, tearing at its flanks with teeth and sharp claws. It's an average day in southern Texas, 115 million years ago. This dinosaur attack happened. We know for certain, because these two animals left their footprints in the mud -- and they're still there, hardened into stone for all to see. Dinosaur Hunt presents this dramatic event and brings the two combatants vividly back to life. It is the tale of a young Acrocanthosaurus, a predatory dinosaur similar to T. rex. As she grows she learns to hide, hunt, and survive in the eat-or-be-eaten age of dinosaurs. The astounding, lifelike art of Karen Carr transports us to this strange and threatening world and re-creates one of the most gripping tales a few footprints ever told. |
