The article says they had found another croc comparable in size in North America

I still would like to see the mathematical model where something that weighs over nine tons and is only as large as a school bus can swim. Maybe the water was several times more dense then than it is now. But even then, let's give the sucker a foot that spans twenty square feet of surface area. Four feet means 80 square feet. That means the beast exerted 32,400 psi just when walking. Is there any swamp that can hold up under such pressures? Or did the croc have huge footprints?

Note, it could be possible, but I'd like to see some real math.

The croc must have been hanging out near the Gulf of Mexico.

Remember, This was millions of years ago. There was alot more water back then. It probably hid underwater and wated for a traveling herd of sauropods and snatched a young one as the crossed.

Okay:

The article says it weighs 18,000 lbs. 1 gallon of water weighs 7.49 lbs. So it would have neutral bouyancy if it occupied 2,043 gallons, or 288 cubic feet. So, if it were 30 feet long, it would have an average diameter of 3.49 feet.

Big, but not THAT big...
