A Jurassic graveyard in Patagonia, Argentina, holds more than 100 fossilized eggs and the bones of 80 Mussaurus patagonicus dinosaurs ranging in age from hatchling to adult. The trove of dinosaur remains suggests that these paleo-beasts lived in herds as early as 192 million years ago, a new study finds.
Meso- means middle. Clearly something is different about Mesozoic sediment compared to Paleozoic and Cenozoic. Paleozoic was the deluge. Mesozoic was the period of time when the water remained high on the Earth.
According to our compilation of doublespeak terms used in Paleobotany and Paleontology "abundant" is a euphemism for eradication. That's what Jurassic sediments preserve: the eradication of dinosaurs.
"Rise of higher insects and birds" is an example of Paleodoublespeak. Jurassic sediment contains the preserved remains of dead insects and birds. That's not evidence of their rise. It's evidence of their extinction.
Statements that the Earth had a uniform equable climate during geological periods are a little misleading. Sediments are assigned to periods based on their flora and fauna, to it's just a little microcosm of circular reasoning.
The Triassic marks a return to the format which we saw repeatedly for the periods of the Paleozoic era. We know that these sediments were deposited during the deluge phase of Noah's flood because of the climate statement.
The Jurassic wasn't a period of time, it was an ecosystem which was adapted to certain conditions of aspect and altitude, determining the flora and fauna, which had world wide occurrence at the time of Noah's flood.
