Re: Holtz v. Sereno???
Concerning the restoration of Triceratops at SVP by Garstka & Burnham, it is
impossible on many counts. All ceratopsid trunk vertebrae clearly articulate
in a gentle arch, not the near dead horse sway back they show. The stance
is very different from the multiple Triceratops trackways (see the latest J
Vert Paleo), and therefore wrong. The scapula was too vertical, and the tail
did not stick straight up like they show! They mistated aspects of my work in
The best talk at the meeting was that by Dave Thomas, who showed that Bird's
old Texas Cretaceous trackway does show a big theropod attacking the tail of
a sauropod. He is almost certainly correct.
