Anyone ought to be able to figure out you do not find many dead dinosaurs down at 10,000 feet.

Precursors to modern moles? Maybe they burrowed their way down there?

Dinosaurs are thought to be bird like, not mammal like.

I would argue the burrowing owl is the possible result of the burrowing dinosaur precursor

My tongue in cheek theory: the dinoaur population was largely comprised of herbivores, and if modern vegans teach us anything, it’s that herbivores are very gassy. All the dinosaur farts caused global warming, which was beneficial and led to even more dinoaurs and more methane.

Until, one day an asteroid came along, igniting all the methane and blowing dinosaur carcasses plumb underground from the intense shockwave. Natural gas is therefore ancient dinosaur farts, and crude oil is what is left of the dinosaurs, what with all the mushing that occurred when they were slammed underground. They were pretty well pureed and blackened by the searing heat.

Heck, it makes more sense than some leftist envirobabble, lol.
