"Extinction of some species." Dead bodies buried in sediment from Noah's flood represent entire flocks, herds and populations of animals. If they were the only living members of their species, that's why they're extinct.
Spread of Grasslands
"Climatic changes in temperate latitudes that allowed the spread of grasslands." Grasslands are a habitat type, not a period of time. The remains of them have been preserved as fossils.
Heavy Rainfall
Scientists disguise the evidence of a worldwide flood by using jargon which is something other than a worldwide flood, but this one is a dead giveaway. "Heavy rainfall." How heavy? 40 days and nights to be exact.
Continued Inundation of Embayments and Synclines
"Continued inundation of embayments and synclines". That's how you describe a world-wide flood without saying the words world-wide flood. This is another phrase to add to our list of Paleodoublespeak terms.
Extensive Inundation of Continents
"Extensive inundation of continents" is letting us know that this was part of a world-wide flood. The inundation is the second phase of Noah's flood.
Dinosaurs Abundant
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
"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.
First Mammals; Rise of the Dinosaurs
First mammals? A place where mammals were buried doesn't make them the first mammals. The presence of mammal remains in sediment is used to place the sediment in timeline of the evolution narrative.
Rise of the Cycadophytes, Ginkgoales
The Triassic wasn't rise of the cycadophytes and Ginkgoales, it's the preserved remains of cycadophytes and Ginkgoales because their habitat was destroyed and buried in a world-wide flood. That's Paleodoublespeak.
Paleodoublespeak
Doublethink is more than authoritarian propaganda of a dystopian society and we (that's me and the Holy spirit) show that it's the heart of the mainstream science narrative of godless existence (SciPop). It's used in descriptions of geological history.
