Not just dinos, but all the freshwater (or saltwater?) fish on board. One or the other must have been on-board or they would have died (too much salinity/not enough salinity).

Not to mention the food for the elephants alone would have consumed 2% of the entire net volume of the ark. That doesn’t include food for other big animals like rhinos, giraffes, zebras, horses, etc.

And that’s at a 50% food consumption rate (half their normal daily consumption) AND assuming the hay is packed as tight as a wire-bound bale of hay; if it was loose-stack (which it most likely was), you’ve got 5% net volume devoted to just food for only the elephants.

Don't forget the waste generated by all these animals.

And how would it have been possible to keep the predators from attacking their fellow travelers?

Who said the animals were all adults. It's very possible they were all very young.
