Based on molecular clocks evolutionist predicted that gorillas appeared 8M years ago , but then we found a 10Myo gorilla in the fossil record . .....but nobody makes a. Big deal, scientist simply say
hey "maybe gorillas evolved earlier"

We used to believe, based on genetic information, DNA studies and molecular studies, that the splits between chimpanzees and the human line on one side and the gorilla line on the other side … happened around eight million years ago," said paleontologist Berhane Asfaw, who helped unearth the fossil. "But based on this new information, the split had to happen before 10 million years ago. It means that information has to be adjusted in every textbook."

If there where feathered mammals in the fossil record, you would simply say that feathers evolved before birds and mammals diverged.
A good and valuable scientific prediction ha to be specific and has to flow naturally and inescapable from the theory. For example eistein predicted exactly how clocks should be affected if you move at such speed. .....you don't have anything remotely analogous with evolution (talking about the fossil record)
.
1 as I told you before some exceptions are expected ...the point is that we do se a trend ....
-marine animals are usually found at the bottom, flying animals at the top.
-intelligent animals at the top, unintelligent at the bottom.
-animals that instinctively run away from disasters at the top, animals that don't have this instinct at the bottom.
We do see this trend and you know it.
2 is not about speed it's about ability to scape from a flood (speed is just one of many important variables) , sloths can climb trees and they instinctively run away from naturally disasters , (t-rex probably didn't had this abilities )
3 modern sloths are slow, but perhaps they had ancestors that where faster
My point is that if one finds a fossil graveyard with rabbits, then by default it would not be precambic layers .....scientist would not date the rock to see if it's Precambrian, and any radiometric dating that concludes that the fossils are billions of years old would be dropped (scientist would assume contamination or something else)
Do you grant this point ?
