Maths time. Now, the formula the amount of food an endothermic carnivore needs per day is x = 0.11(mass in kg)^0.75. Your average
Tyrannosaurus rex massed 5000 kg, and that's being generous on your part. That's about 65.4 kg of meat per day. Noah's Ark floated for one year, according to the Bible. For two
T. rex, assuming they would be unclean, that would mean Noah would need about 47746.7 kg of meat, and would need it to remain edible for that time. Now, meat's specific gravity is around 0.9, if I remember correctly, so that would take up around 53 cubic meters of space.
Now, let's extend this to the other large, predatory dinosaurs. Like the 4500 kg
Spinosaurus. Or the 8000 kg
Giganotosaurus. Or
Carcharodontosaurus, which massed around 5000 kg.
Tarbosaurus is another 5000 kg beastie, as is "Megalosaurus"
ignens, the giant ceratosaurid.
Just those five animals boosts the amount of meat needed to around 303,031.1 kg of meat, which would take up around 336.7 cubic meters.
I can go on, if you want. There's dozens more theropods that mass around the ones I've already shown, and hundreds that mass less.
