Coloradian period as divergent speciation and the other less drastic changes as phyletic speciation.) Define the following terms: morphology (the form and structure of an organism considered as a whole.) fossil (A remnant or trace of an organism of a past geologic age, such as a skeleton or leaf imprint, embedded and preserved in the earth's crust) phylogenetic tree (diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor) Examine the fossil that was unearthed in a museum, apparently the labels and other information were lost. Using your fossil record, determine the time period this fossil is likely from. (Middle Montanian) Of the two major species that arose from the parent species, which was more successful? How do you know? (The species with more body segments because there were more occurrences of this body plan in the fossil record) For each of the "blanks" on your fossil record make a sketch of what the animal would look like. Draw these on your fossil record. (Answers will vary)
