Re: First nest of Protoceratops

"The analysis of the 70-million-year-old nest by Fastovsky and his 
colleagues found that all 15 dinosaurs -- at least 10 of which are 
complete specimens -- were about the same size and had achieved the same state 
of growth and development, suggesting they represent a single 
clutch from a single mother. The discovery also indicates that the young 
dinosaurs remained in the nest through the early stages of postnatal 
development and were cared for by their parents."


Possibly, but as there was no mention of adult fossils being found associated 
another alternative hypothesis was that these are all recently hatched young 
that had spent a few days in the nest prior to breaking out all at once. They 
just so happened to get buried before the great exodus.


They represent a creche of individuals that were living in a group independent 
from the adults. This would call into question the assumption that they were in 
a nest, instead of something more like a makeshift bed similar to the ones box 
turtles, deer and dogs make.

I hope the eventual paper covers these alternative scenarios.
