Re: Dinosaur Planet, parts 3 & 4

Since Tom raises this issue:
"There is now a cliche of the "hordes of newly hatched sauropods running for 
saftey in the trees" sequence, for which there is NO positive evidence. 
Simplest assumption by phylogeny: sauropod parents stayed near their own
young through hatching into the first few weeks of life."

I would take strong exception to this, noting that the "evidence" for parental 
care in the Dinosauria (even Jack's Maiasaura) is very weak and based mostly on 
inferences and assumptions. What evidence there is indicates that the smallest 
footprints in track sites are half- or more adult size. There are NO baby 
tracks with adults.
