Re: [Geology2] Newly discovered baby Titanosaur sheds light on dinosaurs' early lives
So I wonder what killed them so suddenly they were preserved and kept their
bodies together.... the paleoenvironment was flood plain, not volcanic and
no mountains for landslide.... a flood or tsunami event would seem to
separate bodies from each other... so what happened to this mother and baby
dino?
------------------------------------
Unless I've missed something the article doesn't actually say they found both the mother and hatchling and I would guess they only found the young one there. On the topic of sudden death and preservation, flood plains adjacent to mountainous areas are ideal locations for preserving animals during flood events, and especially where the climate is normally dry. When wildfires stripped the vegetation off the mountain slopes around Colorado Springs a few years ago, the sediment apron along the front of the mountains became very vulnerable to sudden large scale flooding and mass movements of sediment that was no longer held down by plant roots. Sudden heavy rains along the higher elevations dumped a lot of water that began to pick up dirt as it moved down and out over the dry dusty land and turned into roiling mudflows. They follow the arroyos, sweeping down without warning, under clear sunny skies, and they have a nearly vertical leading edge that is several feet high which, because of its high viscosity, can exert considerable force.. Some of the arroyos have steep walls, and there would be no way to swim out of the deluge. When I saw this on video a light came on in my head. I suddenly knew why there were so many dinosaur bones in the rocks along the Front Range.
