Majungasaurus
Majungasaurus was a carnivore (meat-eater) that lived in
Madagascar during the
late Cretaceous period,
between about 70 and 65 million years ago.
It was one of the last dinosaurs, and probably became
extinct
during the the
Cretaceous-Tertiary mass
extinction.
Majungasaurus was a large predator which walked on its two hind legs. It probably was about 20 to 23 feet
(6 to 7 meters) long, and weighed over 1 ton. It had short arms, and a wide skull with with a short snout
caped by a single rounded horn.
The only known herbivores at the time in the region were
Sauropods
such as Rapetosaurus, and it is therefore thought that Majungasaurus
must have feed on them. Scientists have suggested that Majungasaurus was adapted to feed on on
Sauropods (which
would have been very powerful animals). Its skull, jaw and teeth suggest that it would have attacked its
prey using a bite and hold attack (similar to the hunting strategy of modern cats),
rather than the strategy probably used by most other
Theropods
of taking many bites (similar to the strategy used by modern dogs and wolves).
Additional evidence that may support this theory is that Majungasaurus, as compared to most
Theropods,
had relatively short and stocky legs, and a low center of gravity.
Majungasaurus is also known to have engaged in cannibalistic behavior
(at the time of writing, the only other dinosaur that has also been suspected of cannibalism is
Coelophysis,
however in the case of Coelophysis,
there is some doubt over it was in fact a cannibal).
The evidence for Majungasaurus being a cannibal is that
fossil
bones of the animal (and as well as
fossil bones of
Sauropods
that lived in the region), have been found showing teeth marks made by other
Majungasaurus.
It is not known however under what circumstances Majungasaurus would have engaged in
cannibalism - it may have actively hunted its own kind, or it may simply have scavenged carcasses of other
Majungasaurus. One possibility is that if two Majungasaurus fought over a killed prey animal, and one was kille during this fight, then it would have scavenged its rival's remains (this type of behavior is found in
some modern animals such as Komodo dragons).
Majungasaurus was a carnivore (meat-eater) that lived from 70 to 65 million years ago

Majungasaurus Facts
Here is a summary of some of the key facts about Majungasaurus:
- Majungasaurus was a genus of dinosaur.
- "Majungasaurus" means "Mahajanga lizard". It is named after the Mahajanga province of Madagascar - the reason the name uses an older spelling of the province's name.
- Majungasaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Majungasaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
- Majungasaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Majungasaurus was not itself an ancestor of birds).
- Majungasaurus lived between about 70 million years ago and 65 million years ago, during the late Cretaceous period.
- Majungasaurus was one of the dinosaurs which died out during the Cretaceous-Tertiary mass extinction at the end of the Mesozoic Era.
- Majungasaurus lived in Madagascar.
- Majungasaurus was a carnivore (meat-eater).
- Majungasaurus was about 20 to 23 feet (6 to 7 meters) long.
- Majungasaurus weighed over 1 ton.

Extracto: Majungasaurus ("Mahajanga" + gr. "lagarto" = "Lagarto de Mahajanga") es un género de dinosaurios terópodos abelisáuridos que existieron a finales del período Cretácico, hace aproximadamente 80 millones de años, en el Campaniano, en lo que hoy es Madagascar. Solo una especie, M. crenatissimus, ha sido asignada. A este género solía llamárselo Majungatholus, nombre que ahora se considera sinónimo de Majungasaurus. Al igual que otros abelisáuridos, el Majungasaurus era un depredador bípedo provisto de un hocico corto. Aunque los brazos no disponen de mucha evidencia, se reconoce que estos eran muy pequeños, mientras las patas eran largas y robustas. Por otro lado, se diferencia de los demás abelisáuridos al contar con un cráneo más ancho, dotado de una textura muy áspera y endurecida en el tope del hocico, más un cuerno redondeado arriba del cráneo, el cual fue originalmente confundido con el domo de un paquicefalosauriano. También poseía más dientes en ambas mandíbulas que la mayoría de abelisáuridos. Tras ser conocido por numerosos cráneos y esqueletos bien preservados, el Majungasaurus ha llegado a ser uno de los dinosaurios terópodos más estudiados del Hemisferio Sur. Aparentement... |

Among the exciting events in recent dinosaur paleontology has been the discovery of significant numbers of dinosaur fossils in South America, many of which are markedly different from their cousins to the north. Fernando E. Novas, one of the scientists closely involved with these important discoveries, presents an up-to-date and comprehensive overview of the dinosaurs of South America. Novas reviews the dinosaur record in the region from Patagonia to Peru, discussing the anatomy, systematics, and evolution of these dinosaurs (and their immediate precursors) within both paleogeographic and paleoecological contexts. He describes all of the important finds in chapter-length studies of the Triassic, Jurassic, and Cretaceous periods. Because the Cretaceous record is so rich, Novas devotes separate chapters to sauropods, theropods, and ornithischians, and puts together the evolutionary story of the period in a final summary chapter. Generously illustrated in color and in black and white, The Age of Dinosaurs in South America is a first-of-its-kind report on these unique and wonderfully diverse dinosaur faunas. (2010) |

Although African dinosaurs make a significant contribution to palaeontology, they are often omitted from books in favor of better-known species like T. Rex. But their fossils have been discovered across the continent - from the Sahara Desert and the dusty plains of Kenya and Tanzania to the sandstone flats of the Karoo - and they are no less magnificent or fascinating than their 'celebrity' cousins. Famous Dinosaurs of Africa is written for children, but has broad appeal for anyone interested in learning more about dinosaurs. A brief general introduction is followed by short chapters on dinosaur species, among them those that were fish-eating, sociable, predatory, etc, as well as those that were cannibals, and the biggest meat-eating dinosaur of all time - the thread being that they all come from Africa. Details are given about where they were found, the meaning of their scientific names, and their size and diet. Spectacular, colorful illustrations bring the creatures vividly to life; photographs, maps and line drawings further illustrate the subject, while 'Unsolved' and 'Up-close' panels add to the intrigue. With a large, pullout poster, this is a most attractive and inspirational book. |

This captivating book, laced with evocative anecdotes from the field, gives the first holistic, up-to-date overview of dinosaurs and their world for a wide audience of readers. Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more "new" species were named than in all prior history. With these discoveries--and the most recent controversies--in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story. |
