An Argentine-Swedish research team has reported a 70-million-year-old pocket of fossilized bones and unique eggs of an enigmatic birdlike dinosaur in Patagonia...

The dinosaur represents the latest survivor of its kind from Gondwana, the southern landmass in the Mesozoic Era. The creature belongs to one of the most mysterious groups of dinosaurs, the Alvarezsauridae, and it is one of the largest members, 2.6 m, of the family. It was first discovered by Dr. Powell, but has now been described and named Bonapartenykus ultimus in honor of Dr. José Bonaparte who 1991 discovered the first alvarezsaurid in Patagonia...

The two eggs found together with the bones during the expedition might have been inside the oviducts of the Bonapartenykus female when the animal perished. On the other hand numerous eggshell fragments later found show considerable calcite resorption of the inner eggshell layer, which suggest that at least some of the eggs were incubated and contained embryos at an advanced stage of their development.

It would be most excellent if the late stage embryos in the egg fossils displayed any trace of feathers.

Now that would make some good thousand year old egg..

[Dr. Bogus Pachysandra]

Tastes like chicken!

[SunkenCiv]

:’) There is more of gravy than the grave about it. ;’)

[SunkenCiv]

It should be checked for traces of Iocaine powder.

Also, an oversized fossil bunny...

How do you find a unique egg?

That Gabriel Lio isn’t a very good Illustrator. Where’s the little red plastic thingie that pops out when they’re done?

[SunkenCiv]

Shell if I know.
