Question
Objectives Develop 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 interesting. 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.nhm.ac.uk/nature online/life/dinosaurs-other-extinct-creatures/dino-directory/index.html). You can search by 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. 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 8 Problem 2 8 Problem 3 8Explanation / Answer
Problem 1: Prosauropods
Anchisaurus resembled lizards and were dog-sized Dinosaurs that hopped around while foraging their surroundings for food. Earlier studies mention that these species were omnivorous while recent studies mention that they were in fact herbivores.
Anchisaurus actually were bipedal as well as quadrupedal beings. Digestion in herbivores is actually a lot more complex and needs a bigger gut. Being bipedal, the position of the gut was uncomfortable- causing the species to evolve into quadrupedal. Since their digestion was weak, they ingested gizzard stones to digest their food.
The Anchisaurus had spoon shaped teeth that were serrated to rip off leaves from plants, narrower feet and actually could manage to use their front two feet (with a reversible first finger used similar to thumbs in human beings) to grasp things. They had sharp clays that helped them to defend themselves from predators and to grasp branches of trees.
The feet consisted of five toes that could lay flat against the ground and could bear weight at the ankle. Although their locomotion was usually on all four legs, they could assume bipedal position to reach taller plants.
Even though their geographic location is restricted to North America, footprints of these species is discovered at Nova Scotia.
