A group of Mahakala (miniature raptors) tries to bring down a Psittacosaurus while avoiding its powerful beak and its poisonous bristles... NOTE- I realized too late that Mahakalas lived millions of years after Psittacosaurus. So what...
JURASSIC PARK Los Archivos Perdidos Dilophosaurus Epoca: Jurasico temprano, hace unos 200-190 millones de años Distribucion: America del Norte, Asia Longitud: 7 metros Peso: 500 kgs Dieta: Carnívoro Apodado "escupidor", el Dilophosaurus es uno de los dinosaurios mas representativos de Jurassic Park. Recibe el apodo porque puede lanzar una sustancia negra y viscosa a los ojos de su victima hasta a una distancia de varios metros. Esta sustancia es de hecho un coctel de siete enzimas toxicas distintas, las cuales causan intenso dolor y ceguera, dejando a la victima indefensa ante el ataque del Dilophosaurus. Tambien puede inocular su veneno mordiendo y masticando a la presa antes de soltarla y esperar a que muera. Al parecer, los individuos jovenes son mas propensos a escupir. El Dilophosaurus suele ser esquivo y de habitos nocturnos; no obstante, esta entre los dinosaurios mas llamativos por sus crestas vivamente coloreadas y la gola de piel membranosa que puede extender cuando esta a punto de atacar, como la capucha de una cobra. Aunque es un veloz corredor, en Jurassic Park es principalmente un cazador de emboscada que vive en las zonas selvaticas mas inaccesibles. TRIVIA: Los cientificos de Jurassic Park solo se enteraron de que el Dilophosaurus podia escupir su veneno cuando un obrero del parque fue alcanzado de lleno en la cara. Nunca se pudieron localizar las glandulas venenosas del Dilophosaurus. EXTREMADAMENTE PELIGROSO! Veneno hemolitico.
JURASSIC PARK The Lost Files Dilophosaurus Age: Early Jurassic, (200-190 mya) Range: North America, Asia Length: 7 meters Weight: 500 kgs Diet: Carnivore Nicknamed "spitter", Dilophosaurus is one of the most representative Jurassic Park dinosaurs. It gets its nickname from its ability to spray a black, gooey substance to the eyes of its victim to a distance of several meters. This substance is actually a cocktail of seven different toxic enzymes, which cause extreme pain and blindness, leaving the victim defenseless against the Dilophosaurus' attack. It can also inoculate its venom by biting and chewing prey and then releasing, waiting for it to die. It seems that young individuals are more prone to spit. Dilophosaurus is elusive and nocturnal; however, it ranks among the most spectacular dinosaurs due to its vividly colored crests and its frill of membranous skin that can be expanded like a cobra's hood when the animal is ready to attack. Although it is a fast runner, in Jurassic Park it is mostly an ambush predator that lives in the most remote jungle zones. TRIVIA: The scientists of Jurassic Park only realized that the Dilophosaurus could spit its venom when one of the park's workers was hit in the face by the animal's spittle. The Dilophosaurus' venom glands were never found. EXTREMELY DANGEROUS! Hemolytic venom.
Dilophosaurus wetherilli is named for the explorer John Wetherill, whose nephew informed the fellows at the University of California's Museum of Paleontology (UCMP) of the finds of several specimens near Kayenta, Arizona in the then-Triassic near-Chinle rocks as they were known. Two skulls have been recovered and noted to date, but the first was in pretty terrible condition, while the second preserved a pair of crests. This gave Samuel P. Welles, then at the UCMP, the honor of naming one of the more famous of Jurassic Park dinosaurs Megalosaurus wetherilli (John Wetherill's great lizard), and then Dilophosaurus wetherilli (John Wetherill's two-crested lizard).
Here, the skulls are shown with jaws agape (left) and closed (right).
Majungasaurus, a name with history, although not many people really think about it.
In the late 1800's, some odd teeth from Madagascar were given the name Megalosaurus crenatissimus. Those days, virtually all carnivorous dinosaurs of a relatively large size were considered belonging to this "catch-basket" of Megalosaurus, but this would prove problematic when, in the mid 1900s, a lower jaw was found on Madagascar with the same kinds of teeth, but this jaw was very different from that distinct Megalosaurus bucklandii jaw, curved and with rough texturing on the outside. It was given the name Majungasaurus, the "lizard from Majunga", a name for the region where the fossils were found. Not long thereafter, a small portion of skull was found and given the name Majungatholus atopus, and was considered a weird pachycephalosaur. With new discoveries of skeletons on Madagascar, these fossils can all be considered the same animal, and the first name has priority, thus ... Majungasaurus crenatissimus.
Note on anatomy: Not all of the bones come from a single animal. Many different animals are known, but some only preserve a few of the bits and pieces, which makes composing a single skeleton tricky as some of those individuals are smaller, younger, than others. This is done here with elements scaled to "fit" to the largest specimen that is the most complete, which includes the skull. You get a long, low-bodies, short-legged, stumpy-armed, and weird-headed animal.
Holidays... it´s raining a lot here... so I´m using my free time at home to finish this Concavenator corcovatus piece that I´ve started when this bizarre theropod was announced... full body version soon...
My interpretation of the fish eat fish idea, but during the Triassic. Eoraptor has caught a small lizard, and might itself become lunch for a Herrerasaurus. This piece was picked for a juried dinosaur art show at the Denver Museum of Natural History.
