Stampeding Dinosaur Tracks Made in Water

What were these dinosaurs running from?

Science Daily reported that dinosaur trackways in Australia, formerly presumed to have been made by a stampeding herd on land, were actually formed in water.  “Queensland paleontologists have discovered that the world’s only recorded dinosaur stampede is largely made up of the tracks of swimming rather than running animals,” the article began.

Some of the tracks look like vertical impressions of toes; others are long grooves.  These would fit impressions made as the dinosaurs – at least the smaller individuals – were partially buoyed up by water.  Larger individuals left flat footprints as if wading up to their legs.  The tracks are identified as ornithopod, ranging in size from chickens to ostriches.  The tracks are found in sandstone and siltstone near Queensland and Lark Quarry.

The new interpretation changes the scenario from a stampede to a river crossing, the article said.

The question they are not asking is, How did footprints in water get preserved?  Wouldn’t such vulnerable impressions get washed out quickly if made in a shallow river?  Wouldn’t dinosaur tracks like this be ubiquitous around the world, if made the way these evolutionary paleontologists assume, in shallow rivers over millions of years?  There should have been numerous rivers in the paths of numerous dinosaurs like this.

The dinosaurs probably knew something the scientist’s don’t: flood waters were coming, and a huge wall of sand– and silt-filled water was aimed right at them.  They were running for their lives.  This was a rare, catastrophic occurrence, the last thing they would have seen.
