Objectives lop an understanding of the two groups of sauropodomorph dinosaurs Learn details of three different genera of the two major groups of sauropodomorph dinosaurs. Instructions Use web-based resources including museum websites and other academic websites to obtain information about three different genera of prosauropod and sauropod dinosaurs. You should identify one genus of prosauropod, one genus of Jurassic sauropod, and one genus of Cretaceous sauropod that you find interestirg. For each genus obtain the information listed on the answer sheet. A good starting point for this exercise is The Dino Directory hosted by the Natural History Museum of London (http://www.n online life/dinosaurs-other- extinct-creaturn "body shape" to sort out the different types of sauropod dinosaurs. Once you've identified a genus that you are interested in, this website can provide you with much (but not all) of the information that is required. You can then begin searching for other sites on the internet and your textbook using the genus name for additional information. If you cannot find enough information to fully answer all of the questions in terms of content and length, you should choose a different genus. index.html). You can search by Completed answer sheets should be submitted through Blackboard. This exercise is due by Friday, June 22 at 5:00 pm. Late exercises will be penalized 5 points per day Grading This exercise is worth a total of 24 points, Points will be earned using the following rubric: Problem 1 8Explanation / Answer
Problem 3: Sauropods- Cretaceous
Fossils were first found in India
The Titanosaurids were the biggest Dinosaurs and one of the last species of Sauropods to live on the planet before the mass extinction of the species took place.
These animals were more evolved than some of the other Sauropods who lived in the Jurassic period. They had a number of adaptations- the neck was shorter than the ancestors and since the weight of the neck reduced, the hollow bones of the vertebrae disappeared in these species. They had strong bone plates on the dorsal side that was meant to protect them from predators and they also had a more flexible spine than their ancestors.
The teeth were spoon shaped like their ancestors but were evenly spaced and unlike the early sauropods (who were bipedal or quadrapedal by choice), the Titanosaurids could only walk on their four feet.
The had stubby, thick legs, a long neck and a body that had bony plates with ridges (for protection). They exhibited a sense of community and always lived in herds. The females of the herd would lay eggs together in a hole in the ground (every female would lay around 25 eggs) and would hide the eggs with plants and shrubs.
Fun fact- In spite of its entire neck and body skeleton being discovered almost everywhere around the planet, the skull of these species is still not found!
