EOTYRANNUS SKULL
On the skull of _Eotyrannus_, Michael Lovejoy asked...
(firstly, sorry for the delay: I've been at the _Leedsichthys_
dig in Whittlesey, Cambridgeshire)...
--------------------------
Problem is, using Fig.3, the left max. as preserved works
out at approx. 189mm, but using Fig.7 the same bit works
out at 267mm! Dunno if I'm doing something wrong, but I'd
be very grateful if someone could please give me sizes for
any of the preserved elements of Eotyrannus.
--------------------------
A cock-up was made somewhere along the line, but right
now I'm not sure when. In Fig. 7 the magnification for the
maxilla (7D) is given as 'x 1', so it should be about lifesize -
viz, preserved length along toothrow of 94 mm.
--------------------------
(The nasal's 220mm, that's all I've got. Oh, and just to
display my total ignorance, is the bit at the bottom of the
page the part that contacts the lacrimals? )
--------------------------
If you're referring to Fig. 4, then yes part of the rostral
process of the lacrimal would have bordered the
caudolateral edges of the nasals but exactly how they fit
together is uncertain: there is a recess for the dorsal end of
the lacrimal though. However the rostral process of the
lacrimal does not project rostrally to fit into that odd lateral
recess located mid-way along the sides of the nasals: that's
something else. So far as I can remember, the main vertical
bar of the lacrimal is straight, there is no lacrimal cornual
process, horn or whatever, and the lacrimal's dorsal surface
is not rugose. Of course for the whole story you'll have to
wait for the monograph.. this'll appear some time around
2025.
--------------------------
So, Darren, you're not "defending the 'Valdoraptor' genre
with terminal intensity", then? :)
--------------------------
No, though I did think that Jar-Jar Binks made the ewoks
looking like.... ****ing Shaft. It's been (insert number of
months) since The Phantom Menace but it still hurts. And a
particularly timely quote (in view of Rise of the Machines,
premiering here tomorrow): 'Vieno tormente'. Funnily
enough, I'm lending both series on DVD to a volcanologist
tomorrow..
