Smooth Change in the Fossil Record

When I was first learning about evolution, one of the things that I really wanted to see was smooth, gradual transitions in the fossil record. I didn't want to see fossils based on part of a jaw bone, or a series of creatures very different from each other being displayed as relatives.

It's taken a lot of looking into the subject before I finally found these examples. I'm going to list examples, and then follow it with an article that explains the transition:

Hominid (Human) Evolution

Reptile to Mammal Evolution

Horse Evolution

Keith Miller discusses several transitional sequences (including the two above)

Whale Evolution Chart

Whale Evolution Article*

Ceratopsian Evolution

The Dilemma of the Horned Dinosaurs (Discuss the Ceratops)

Early Vertebrate Evolution

Several Misc. Examples of Smooth Transition

Early Amphibians

* Since the article on whale evolution was written, a more complete Pakicetid fossil was discovered:
