HISTORY OF TREE-CLIMBING THEROPODS
Given some of the recent discussion on DML about possible
scansorial (tree-climbing) behavior in non-avian theropods,
I thought some people might find the following interesting.
The claim that no, or hardly any, workers have favoured the
notion of tree-climbing theropods is not so. In the following
Naish, D. 2000. Theropod dinosaurs in the trees: a historical
review of arboreal habits amongst nonavian theropods.
_Archaeopteryx_ 18, 35-41.
- . 2000. 130 years of tree-climbing dinosaurs:
Archaeopteryx, 'arbrosaurs' and the origin of avian flight.
_Quart. J. Dinosaur Soc._ 4 (1), 20-23.
... I listed and reviewed all comments in the literature on
possible scansoriality among non-avian theropods. In
chronological order, the following workers favoured or
suggested the existence of tree-climbing theropods
(fictional works are excluded); Fox (1866a, b); Swinton
(1936a); Rozhdestvensky (1970); Galton (1971a, b); Paul
(1988a, 2002); Olshevsky (1991, 1994); Bakker (1993);
Nessov (1995); Palm (1997); Chatterjee (1997, 1999).
Note that Fox's articles were as early as 1866, that Swinton
(populariser of the arboreal _Hypsilophodon_ model) liked
the idea of tree-climbing theropods, and that Galton
admitted that scansoriality for small theropods was possible,
even though he had just debunked the arboreal
_Hypsilophodon_. A poll of those who work on theropods
today would _probably_ show that most workers think tree-
climbing was possible for small coelurosaurs, and the
obstacles that have been proposed are largely erroneous.
In much the same way that many noted palaeontologists are
now more than happy to promote feathery non-avian
dinosaurs (note that these are the same palaeontologists who
had previously condemned such ideas as Bakkerian
nonsense), recent and future discoveries will probably lead
to universal acceptance of the idea of tree-climbing
