And with further searching... it's a bad place and time to be.
Carnotaurus, 30 ft. meat-eater. Human = mid-day snack.
Giganotosaurus, 45 ft. meat-eater. Apparently recently determined to be outclassed by the African genus Spinosaurus, but otherwise ranked the largest land predator known. Human = appetizer.
Argentinosaurus, 115 ft. plant-eating giant. Big chance of accidental damage to a too-close human.
At least one later-era raptor has been found in the region, so at least one velociraptor-class species is likely at the time in question. Human = lunch.
