Re: juvenile bird fossil ref?

"Are juvenile Mesozoic birds often or rarely found as fossils?"
There's also this:
Sanz, J. L., Chiappe, L. M., Fernández-Jalvo, Y., Ortega, F., Sánchez-Chillón,
B., Poyato-Ariza, F. J., Pérez-Moreno, B. P. 2001. An Early Cretaceous pellet.
Nature, 409, 998-999.
... which desribes a regurgitated pellet containing four juvenile bird
skeletons. That they apparently represent three distinct three species suggests
that whatever animal produced the pellet (suggested to be a theropod or
pterosaur) was a serial chick murderer. It also prooves that a varied diet has
always been the way to go, even in the Mesozoic.
