Dinosaur tracks can teach us more about the day-to-day behavior of creatures like T. rex or the Stegosaurus than their skeletons ever could, says paleontologist Martin Lockley. From a “dinosaur’s lover’s lane” in Colorado to the rocky shores of South Korea, Lockley explores what we can learn from the traces of some of the most impressive creatures ever to walk the Earth.

Paleontologists assumed some holes were courtship marks from dinosaurs? Ok….That’s a stretch considering that dinosaurs were not birds, but more like reptiles.

Birds are by definition also reptiles. They have keratin scales and lay eggs.

Actually that’s incorrect where did you read that information from? Because we now know that birds are more closely related to dinosaurs now than ever… even to the point where some dinosaurs had actual feathers

I was 6 when I discovered dinosaurs, and, yes, I wanted to be a paleontologist when I grew up.

And did you become one?

@Redblack Tichy No, when I went to college (the first time) at CUNY, there were no programs for that. Years later, at another university, I got a B.S. in Zoology/ Conservation Biology, and eventually ended up in retail. However, I worked at Big Box Books, and I got to read new dinosaur books. No regrets.

It quite the leap of assumption to see hole in the ground and then to present that as hard evidence for dinosaurs mating and behavior.
Over the last millions years what are the odds that a hole a dino dug a million years ago would still be surfaced and visible, I mean come on, really.

There’s certain conditions to preserve living records that would need to be present both when the track was made and also in the environment after their extinction. It definitely isn’t possible to go into any random backyard and find tracks. This is why there’s very common places to go to see dinosaur tracks. Good examples of places to go are Utah and Colorado since the previously lush climate and presently arid climate is great for finding all kinds of prehistoric relics. Think of how natural mummification happens to people and animals, it doesn’t always occur, but you can predict conditions where it would (also dry and extreme hot or cold). My source for a lot of this is actually Dr. Lockley himself, I worked with/under him for a number of years at a dinosaur park in Utah. It’s complicated, fascinating, and worth a deep dive for sure.

@Casper Sweeney it’s literally assumption on assumption on assumption on assumption, I do not believe there are dinosaur nests and tracks still on surface ground, the entire north American plate has traveled across the globe and back, and your telling me those tracks and nests on the surface are still present, I do not believe that, in fact you have to be insane to believe that.

@RitRis weathering exposes older layers of rock which is why dating and looking for arid climates is important in the search. You’re also looking at sedimentary rock which is far above the interior of the earth and the plate tectonics you’re mentioning. You can start with an educated guess, but you still need hard science like dating rock, studying the physiology of dinosaurs and their living relatives, and more in order to make a concrete conclusion on whether you have tracks, a hoax, a false alarm, or something else.
