Lab # 9 - SAURISCHIAN DINOSAURS I (AMNH)

In this third AMNH lab we will look at some of the saurischian dinosaurs: the Sauropodomorpha and Ceratosauria.

For each of the 2 cladograms below:

1. Identify the synapomorphies on the cladogram.

2. Draw this character as it is found in one taxon that contains it.

3. Place these shared derived characters in their functional and ecological context.

4. Identify the autapomorphies (unique derived characters) for each taxon on the cladogram.

5. Draw the autapomorphies for each taxon.

6. Place these unique derived characters in their functional and ecological context.

7. Compare the appearance in time of each taxon with their position on the cladogram. Are any apparently out of order?
