The picture below shows the morphological change in Triceratops through growth.  1) Describe their morphological changes using your own words, and 2) do these changes potentially raise difficulty in paleontological research?

What does a big and commodious abdomen most likely mean for an ankylosaur?

Which of the following taxa belong to the clade Euornithopoda? Select all that apply: 

There are two clades within the group ankylosauria: Ankylosauridae and Nodosauridae. Nodosaurs can be diagnosed by the distinctive acromial process (large knob of bone on the shoulder blade) and parascapular spines (shoulder spines). Below, label the nodosaurid and the ankylosaurid:

Bonus question: Why are Sauropods so fascinating?  Tell me at least 3 unique features.  (If you think Sauropods are lame, tell me at least 3 reasons why they suck.)

Tyrannosauroidae include basal members (e.g. Eotyrannus, Dilong, and Aviatyrannis) and more advanced clade Tyrannosauridae (which includes Tyrannosaurus rex).  Discuss the key differences between the basal members and Tyrannosauridae, and talk about their evolutionary trend.

#7     In this problem, you are tasked with calculating the shaded area within a circle, excluding the area of an inscribed square. You need to print out the final answer of the shaded area to three decimal places.   Hints: Use printf You may want to subtract one shapes area from another to get the total shaded area.  Area or circle :

#21 Within the main method, write the code that will declare a String variable named word with the initial value of “beekeeper”, and will then print the location of the third occurrence of the letter ‘e’ in the word.  The output message will say “The location of the third e in beekeeper is xxxx”. Your code replaces xxxx with the  location of the third e in the word… be careful here. b is at location 0. Hint: Use a built-in String method. Note: hard coding the location will give you zero points for the problem.   In main: public static void main(String args[]) {       //declare your variable(s) here and initialize       //find the location of the third ‘e’      //print that location }

# 15   After this code executes what is the value of result? public static void main(String[] args){int x = 3;int y = 2;int z = 16;double result = Math.pow(x+y, y) + Math.sqrt(z);}

#1 What is the value of a after the code executes? int a = 3;int b = 7;int c = 4;int d = 6; a = b * c – d + a;
