 Phil Senter scoring characters |
• A graduate student
taking a broad cladistic approach to the origin of birds • Purpose of Phil's visit was to study fossil specimens of dinosaurs and other extinct archosaurs, as well as to use the fluid and skeletal collection of extant archosaurs in the lab • Graciously brought along original specimens of Euparkeria and Desmatosuchus for Witmer and Sedlmayr to study |

 Dong Zhiming, Chang Ying-Chien, and You Hailu with Stegosaurus |
• Dr. Dong and You
Hailu toured the lab, met with students, looked at a few specimens, and got a
sense of what kind of research goes on in the lab • Dr. Dong and Witmer discussed the possibilities of future collaborative projects in China & the US and of training opportunities for Chinese graduate students in Witmer's lab • Chang Ying-Chien (Athens), a veteran of many dinosaur expeditions worldwide, hosted a delightful reception for Dr. Dong and Hailu |

 Rob Hill studying the juvenile skull of Pinacosaurus. |
• A graduate student
working on the evolution and systematics of armored dinosaurs • Purpose of the visit was to examine the original fossils and casts of armored dinosaurs in the lab (e.g., Pinacosaurus, Edmontonia, Stegosaurus, Gastonia, Pawpawsaurus) • Also, studied armor of extant animals in the lab such as that of crocodilians |

 Greg Paul reconstructing the skull of the small theropod dinosaur Deinonychus. |
• One
of the very few premiere dinosaur artists that also is an empirical
scientist • Visited the lab to study the complete collection of the known skull material of Deinonychus • In close collaboration with Witmer, he drafted new, highly accurate reconstructions of the skull of Deinonychus • Will join Witmer and Des Maxwell in publication of the findings |

 Debbie Wharton sagittally sectioning an ostrich head. |
• A graduate student studying
brain and endocranial evolution in archosaurs • Goals were to get an exposure to the lab and its techniques and perspectives • Studied both fossil dinosaur and modern archosaur skull material; used the cleared-and-stained collection; used the Julian J. Baumel Fluid Avian Specimen Collection • Collaborated with Jayc Sedlmayr on a study of dural venous sinuses in archosaurs, via vascular injection |
