Well, I certainly regard Dougal's speculations as *interesting* but I
wouln't call them excellent. For lots and lots of discussion on _The
New Dinosaurs_ search the archives: use the words Dougal Dixon and
perhaps the book title too. Many of Dougal's animals were improbable,
unrealistic or modelled too closely on living or recently extinct
animals (such that there were panda dinosaurs, koala dinosaurs,
glyptodont dinosaurs, snake dinosaurs [ugh] etc etc etc): this was
covered in depth in Greg Paul's review of the book (also discussed in
the archives). So, to sum up: archives archives archives, use the
archives. They are at: http://www.cmnh.org/fun/dinosaur-
And what is this Greg Bear stuff? Is this a book?

Yes the paper is out - I cited it on the vrtpaleo list not long ago I seem
to remember. Dino Frey is the first author. Don't have the ref with me
now - will send it next week. One of Storch's primary reasons for
interpreting _Leptictidium_ [:)] as a strider rather than a hopper was
that it has an unfused tib-fib: all saltatorial placentals have fused tib-
fibs. However, kangaroos do not have a fused tib-fib so this is hardly
concinving. Frey et al. found that the best analogue for _Leptictidium_
"If the Patterson film is a hoax, it is an extremely elaborate one; and
what is most surprising, given the immense amount of study devoted
to it, is that it has not been definitively exposed"
