The photo here on the left, from the cover of Nature Magazine, December 21-28, 1995 Volume 378, shows the mother Oviraptor shielding her nest from the unfortunate disaster which recorded this moment in time. It's discovery in 1993, again by a team of researchers from the American Museum of Natural History, is proof that this was, in fact, a caring parent defending her nest !

This a well-known photo of a fossilized combination burrito plate, made from burritosauruses, rice, and beanosauruses. It was probably made in the early Quesadillan era, where similar constructs have been found, alacartus, without the rice and beanosaurus sides.
