Dr. Bonnan’s Dinosaurs*

*A cute title for this page, but no dinosaur discovery is made alone.  The dinosaur discoveries described on the following pages were made by a team of people, and I was privileged to be in the company of these fellow scientists.  My contributions to these discoveries and descriptions are no more nor less than everyone else’s efforts.  The sum is always greater than its individual parts.

I have participated in discovering two dinosaurs that are new to science, and both of these fossils are from South Africa:

• Aardonyx celestae, a transitional sauropodomorph dinosaur that sheds light on the evolutionary transformation of the common ancestor of sauropods from a bipedal plant eater to larger, quadrupedal, bulk-browsing herbivores.
• Arcusaurus pereirabdolurm, a juvenile, relict sauropodomorph that suggests the traditional “prosauropods” were not dead yet in the Early Jurassic, and still were part of the larger dinosaurian fauna.
