I have a new mystery fossil for you this week. I thought I would put a new fossil off until next week, but considering that next week is Spring Break for many around here and that new, cool research has been published on this animal recently, I decided to go ahead and put it out there.
This is a drawing of the vertebra made by Sir Richard Owen, one of the greatest minds in paleontological taxonomy of the 19th century. The fossil had been identified as one thing, but Dr. Owen provided a thorough and convincing discussion of why that interpretation was wrong. The name given to it was rather humorously coincidental, considering what it turned out to be. It is difficult to identify isolated vertebrae, so I’ll give you another drawing of the same animal, but different parts.
This image is by the person who originally described the earlier vertebra, but also includes a few more pieces.
See if you can take the images, along with my clues, and figure out what this is. We’ll see if anyone can do better than the original descriptor.
