Re: Sauroparental care
Well, as illustrated in the recent dinosaur special, the sauropod nests were
Is there PROOF that they were left open like that? I assume that the
discernable "mound" structure was evident in fossil form and not simply
If an animal is creating a mound, and leaving its eggs exposed, they are
exposed for a reason--and I'm sure they weren't turning the eggs.
I can't think of any "drop and leave" species that DON'T bury their eggs, and
even crocs don't simply bury them, they build mounds.
Funny, the only birds that don't "care" for their young build elaborate mounds
to incubate their eggs much like crocodiles, testing the temperature and
removing/adding compost, allowing the heat of decomposition to incubate their
eggs rather than their body heat.
I havn't put much thought into this, but I wonder if the behavior(of the birds)
was ancestral rather than a recent adaptation. It seem to be strikingly
crocodilian, even just the buried egg alone is kinda "un-birdy".
