tippy toes were touching bottom.

Makes sense ... Thanks SunkenCiv. Also explains some fossilization recovered.

I will display my abject stupidity --

I'm a theropod, I'm in water up to my neck (per the picture) and I'm swimming along, my feet occasionally making contact with the bottom of the river, leaving some footprints for posterity.

Can someone please explain to me the mechanism whereby the footprints stay in the mud, the river eventually ceases to flow, the water that was the river evaporates (how long does that take?)-- throughout all of this, the mud still hangs on to the precious imprint of my footprints -- then, the mud bakes in the sunlight and eventually becomes rock, and millions of years later people look at the rock and say "Aha! This was once mud, about 8 ft underwater, and a theropod stepped on it and left a footprint!"

I've been in rivers, streams, lakes, and ponds. I have stepped in mud. I have left footprints. They last less than a minute. Not a single one of my footprints in an underwater environment has yet become a fossil. What am I doing wrong?

Neat !

Would the head really be up like a periscope or cleaving the water like darned near every other swimming animal?

How did they ever learn the theropod's name?

There is film of Komodo dragons swimming in the sea between islands.

Also film with elephants, bears and snakes swimming. If it has lungs to fill with air, it can swim.

Can anyone think of a mammal or reptile that CAN’T swim—at least for short distances.
