....the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. Genesis 7:11
"Scientists have presented a stunningly preserved leg of a dinosaur. The
limb, complete with skin, is just one of a series of remarkable finds
emerging from the Tanis fossil site in the US State of North 
Dakota.
The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth.
Along with that leg, there are fish that breathed in impact debris as it rained down from the sky.
We
see a fossil turtle that was skewered by a wooden stake;
the remains of
small mammals and the burrows they made;
skin from a horned
triceratops;
the embryo of a flying pterosaur inside its egg;
and what
appears to be a fragment from the asteroid impactor itself.
The North Dakota fossil site is a chaotic jumble.
The
remains of animals and plants seem to have been rolled together into a
sediment dump by waves of river water set in train by unimaginable earth
tremors. Aquatic organisms are mixed in with the land-based creatures." BBC
--OR-- The debris that rained down was due to asteroids pounding the planet to bust apart the plate of the earth thereby opening the great deep and the waves of water was from the flood. Hence the aquatic and land creatures buried together with plants....just saying...
