About Matthew F. Bonnan, Ph.D. (February 5, 1973 - )
Matthew Bonnan[1] is an American paleobiologist and an associate professor of biological sciences at Western Illinois University. His research combines traditional descriptive and anatomical study with computer-aided morphometric analysis and modeling of vertebrate skeletons. Dr. Bonnan also co-directs the Functional Morphology and Evolutionary Anatomy (FMEA) lab with his wife, Dr. Jessica White[2], at Western Illinois University.
The focus of his research is limb functional morphology in dinosaurs, as well as the broader locomotor and evolutionary implications of size. He is particularly interested in the evolution and locomotor adaptations of the giant, terrestrial sauropod dinosaurs. The long-necked herbivores attained sizes no other dinosaurian or mammalian group has ever approached on land; part of sauropod success as giants may be tied to limb morphology and specializations.
Dr. Bonnan teaches a variety of anatomy-based and evolutionary biology courses at Western Illinois University covering diverse topics such as vertebrate embryology, comparative vertebrate anatomy, vertebrate evolution, systematics, dinosaur paleoecology, and general zoology.

Dinosaurs: Why So Big?
Dr. Bonnan's over-arching research focus is the evolution of gigantism in dinosaurs. To this end:
- he has examined the evolution and shape of the manus (hand) and pes (foot) of sauropods and its relationship to locomotion and weight support[3][4]
- he has studied the relationship between the ability to pronate the manus (place the hand palm-side down) in archosaurs and its expressions in sauropods and their ancestors[5][6]
- he has used geometric morphometrics (geometry-based shape analysis techniques) to evaluate and statistically analyze patterns in sauropod long bone scaling[7][8]
- he has studied the link between bipedalism, sexual dimorphism, and limb proportions in archosaurs using the American alligator (Alligator mississippiensis) as a model[9][10]
- he has searched for and described a new transitional dinosaur (Aardonyx celestae) from the Early Jurassic of South Africa that sheds much-needed light on the beginnings of sauropod gigantism [11]
Dr. Bonnan in the News
In the spring of 2008, Dr. Bonnan was involved with a new Morrison Formation dinosaur quarry in Hanksville, Utah. His expertise in the concentration of Sauropod dinosaurs were sought after by and aided the excavation efforts of the Burpee Museum of Natural History.[12] Dr. Bonnan continues to assist the Burpee Museum in excavated the Hanksville-Burpee site, returning in 2009 with WIU students, and plans to continue this working relationship in the long term.
He is also a co-discoverer of the almost-sauropod Aardonyx celestae[13] which has garnered international media attention[14] and should serve to illuminate the early beginnings of sauropod gigantism.
Understanding Science & Evolution
Dr. Bonnan runs a webpage on science and evolution where he discusses how the so-called "battle" between science and religion is false, and provides interested students and laypersons with information and podcasts on the scope and limits of science[15]
