The First Brachiosaurus

Joyce Havstad, PhD holds the title Philosopher-in-Residence at The Field Museum.* We had the joy of interviewing her about some of the fascinating concepts she researches and explores -- in this case, what is a holotype? And how can paleontologists determine new species of prehistoric life based off of incomplete fossil skeletons? *It's probably the only job title that can compete with 'Chief Curiosity Correspondent', really.
