First Pterosaur Embryo Fossil Discovered
blamanj writes "A fossil embryo, preserved in an almost complete egg was found in the sediment of a lake in Liaoning in northeastern China. The Liaoning embryo has a wingspan of 10.6 inches, indicating that the embryo would have grown up into a medium-to-large pterosaur."
"It is bigger than fossils of hatched pterosaurs, which suggests it probably would have hatched soon."
It is an embryo, a fossilized embryo.

Maybe you are joking.
Humans have gill slits, not gills, and limb buds, not fins or wings. The old saying is "Ontogeny recapitulates phylogeny." It is not exactly true, though. The embryology of humans resembles that of many mammals. It resembles fish embryology, too, but not for as long. We share similar adult body patterns and similar patterning genes to many animals, and our early embryology can looks similar. It is not as if we grow to be fish really early and then keep going since we are more evolved than fish.

no really compelling evidence that exctinction was caused by a meteor as the mainstream media implies.
Barring the really gigantic impact crater in the south of Mexico?
After the Chicxulub crater was found (oddly enough - with a dating of 65 million years) most scientists were pretty convinced that an asteroid (10 km is not a meteorite) killed off the dinosaurs. There may have been other contributing effects, but a 10 km object slamming into the Earth would have done extremely bad things to the planet's biosphere.
