Transcript of Diplodocus
states in the fourth paragraph that it is presumed that the dinosaur lived in swamp environments. Climate Continents The Diplodocus lived in the late Jurassic period.
states under "Diplodocus" that it lived about 150 to 145 million years ago in this time period. Time Period Adaptations and Struggle to Survive Time Period of the Diplodocus Long neck- the Diplodocus had a long neck for reaching food in tall trees
Long tail- for defense, could be whipped around Adaptations Seismosaurus The diplodocus lived on North America. http://www.thebigzoo.com/animals/Diplodocus.asp
states under "Habitat" that it lived in present day Colorado, Montana,Utah,Wyoming, and the Rocky Mountains. When the Diplodocus was alive, the North American continent was a shallow sea and still connected to Europe as part of Pangea, as stated in the third paragraph under "Jurassic" at http://www.encyclopedia.com/topic/Jurassic_period.aspx http://www.bbc.co.uk/nature/life/Diplodocus describes that the adaptions of the Diplodcus were its: http://palaeo.gly.bris.ac.uk/Communication/Trickett/feet.html states that its adaptations were its:
Size- the dinosaur had a sturdy, humungous body that kept predators away
Four sturdy legs- these supported its weight http://www.nhm.ac.uk/about-us/news/2012/july/diplodocus-stripped-branches-at-feeding-time112736.html
Teeth- these teeth were adapted especially for chewing and gripping the vegetation it ate
states that the dinosaur:
Traveled in herds- the text says under "Social Structure" that it may have traveled in herds for protection against the few predators that it did have states that its adaptations were its: Getting Food The Diplodocus was a vegetarian. Its environment consisted of trees and plants that it used its long neck to eat. http://animals.howstuffworks.com/dinosaurs/diplodocus.htm
states that it got its food by moving its long and slender neck from side to side to eat the leaves on trees and some ferns and other vegetation on the ground. Threats to the Diplodocus As opposed to the adult dinosaur, a young Diplodocus was very subject to predators. In the ninth paragraph under "Diplodocus the dinosaur" at http://www.prehistoric-wildlife.com/species/d/diplodocus.html
the text says that the growing Diplodocus faced predators such as the Ceratosaurus and Allosaurus.
Natural selection occured; the mother would produce more eggs than what would survive against the predators. Extinction How did they go extinct? Time Period of Extinction The Diplodocus became extinct in the early Cretaceous period. http://www.dinoextinct.com/page6.htm
explains. The Diplodocus became extinct when Pangea split apart. http://www.dinoextinct.com/page6.htm
states that the dinosaurs' hearts failed to pump blood to their skulls because of the increase in gravity. Contemporaries' Extinction Some dinosaurs who lived at the same time as the Diplodocus went extinct for the same reason and at about the same time. http://www.dinoextinct.com/page6.htm
states that the Aptosaurus, Brachiosaurus, and Camarasaurus went extinct along with the Diplodocus because of the breaking apart of Pangea. http://www.youtube.com/watch?v=r1yv7Pi78Og
