That also says that most (the overwhelming bulk) of all antediluvian remains are beneath the waves. That's probably why we don't find bones of dinosaurs and mammals intermixed.
There are hundreds of thousands of drillholes in continental shelf and slope areas. None of them have ever shown that dinosaurs and mammals have been mixed. In fact, most of these drill holes out to the con shelf show marine deposits. SOme drill holes closer to shore do show some continental deposits but no evidence of mammals and dinosaurs together.
This is a very important "fact" for your hypothesis gunga. Its a falsification statement that is more responsible for revealing your hypothesis as false.
Boringly we seem to find ALL the dinosaurs from the Triassic to the Cretaceous and triconodont,symmetrodont pantothere , and multituberculate mammals all from the Jurassic to the K. Triconodonts and Multituberculates made it into the lower Eocene. MArsupial and Monotremes Appear in the Cretaceous and Placentals dont appear until the lower Eocene. We have excellent stratigraphic control on mammals nd dinosaurs and NOWHERE do we find anything that deviates from that sequence.
We dont have any evidence of dinosaurs and modern mammals living together. The only evidence is of mammals evolving more primitive orders during age of dicosaurs. MOdern mammals like Marsupials and placentals werent even in the fossil record until the Eocene when all dinosaurs had alredy disappeared. Monotremes, do seem to cross the boundary but weve only got a few fossil monotremes and theyre not even certain what a fossil monotreme would bring to the table since most of its characteristics are soft tissue dependent.
We should see , somehwere that mammals, dinosaurs, birds,reptiles and all styles of fish and srthropoda should exist together(Im not even gonna start with evidence about plants, but lets just say that your hypothesis doesnt stand up too well)
When you decide to buck scientific evidence, the only valid way is to present alternative evidence, not a vague statement that "These mammals and dinosaurs are probably out in the wave xone" Thats silly thinking. We often work with multiple hypothesis and then we test them. Thats the only valid way to present theories and advanced hypotheses. Your statements of hopeful ignorance are ludicrous from their face.
You admit that coexistence between mammals and dinosaurs is critical to your worldview, yet you are unable to admit that your explanation is not only without any evidence, it is clearly shown to be counter what scientific evidence already shows.
