Questions from my Guest Book
Lately I've been getting swamped with an absolutely enormous amount of
questions on my Guest Book (I may have to shut the thing down
temporarily...). Here are some I could not answer sufficiently:
- Has anyone heard of a pre-Morrison North American stegosaur (or
thyreophoran, anyway) called "Hesperisaurus"? Apparently it is on display
at the North American Museum of Ancient Life in Utah.
- What are the correct masses for _Ankylosaurus_ and _Euoplocephalus_?
Mine do not appear to be consistent with each other.
- One guest said that, in a book called "Collins Dinosaurs", Chris Brochu
authored this passage:
"For decades it [_Deinocheirus_] was assumed to be a monster carnivore,
but a series of finds revealed that it belonged to an unusual group of
theropods -- the therizinosaurs. They had long necks, small heads, and
teeth that seemed suitable for eating plants. The hips were huge but the
legs and tail were quite short. We now think _Deinocheirus_ was a
dinosaurian version of the extinct giant ground sloth, which sat on its
haunches and used its powerful arms to rake vegetation towards its mouth."
I thought it was generally held to be an ornithomimoid, not a
therizinosaur. What "series of finds" is this? Chris? Somebody?
- Have any studies been done on the running speed of phorusrhacids? (or
gastornithids, for that matter?)
That's it for now....
