Re: The Very Very Latest Paper From 2006!!!
The deer I am familiar with have an obvious double seasonal growth whammy;
winter growth conditions, and the coincident rut. So yeah, I would expect LAGs
in Megaceleros too.
Elk are probably relatively far up the surface/mass ratio chart from elephants
though. I'm just saying that if the LAGs disappear in both the largest dinos
and the largest mammals, AND there are commonly dinos w/ well-defined LAGs that
have significantly smaller surface/mass ratios than the largest (temperate or
cold climate) mammals, then that is relevant to the debate about their
respective thermo-regulatory systems.
If some kind soul w/ access to the data could write them up and publish them,
perhaps someday I can search under keywords "LAG, definition gradient". }:D.

Maybe so. But I think one would find fairly pronounced
LAGs in _Megaloceros_. But I have not read this:
which is apparently about the deer thriving in an
environment (and under nutritional conditions) that
were previously unknown for this species.
