Re: Dinosaur environments
Somebody (Krentz?) said -- "It certainly made the experience much more
meaningful and somehow made those trees even BIGGER in stature. It was OK if
our dinosaurs looked small next to them! On an artistic level it's the same
thing Doug Henderson has done for years."
The last time I took a serious look was 10 years ago, but I saw nothing then in
the geo-record to approach the extant CA Redwoods in size, or even the trees
mentioned in historical accounts 1600 to present. The largest fossil diameters
afaik are 3-4m, Miocene (IIRC), at Florrisant. There are some Devonian stumps
nearing 2m in diameter.
As I don't see a reason why large stumps would not be preserved at some point
(there seem to be many whole stumps preserved by ashfalls), it may be that
trees did not get as big in dino-time environments as they do now.
Again, it may be preservational bias, but there seems to be an overarching
trend in the record through geo-time toward increasing size in trees -- and it
is possible that the largest trees ever are Holocene. The most remarkable thing
about this apparent trend is that it is largely un-noticed or ignored by
I mostly post this in hopes someone is aware of data I have not seen (in SA,
perhaps?) or is willing to otherwise comment -- but "redwood-sized" trees may
be a stretch dat-wise in dino-scapes.
