Because the Diapsid reptiles (Dinosaurs in Particular) were seen as the dominant terrestrial life forms during that time, being both the Apex predators, and the largest herbivores. Odds were if you saw a vertebrate on land, it was a reptile. Additionally, during that time, reptiles also took to the sea in a far greater variety than seen today (and got quite large as well, Pliosaurs were likely Apex predators in the sea as well) That period was seen as a high point for reptiles - mammals now occupy most of the niches that reptiles did in the mesozoic. Additionally, when that phrase was made, Birds were not considered to be a highly derived/specialized reptile, further increasing the apparent contrast between reptile abundance now, and the much greater reptile abundance in the mesozoic. .... Although when that phrase was coined, the "proto-mammal" synapsids were considered to be reptiles, with the more advanced synapsids being called "mammal like reptiles" (they are no longer considered reptiles) So I must wonder why the term didn't originally refer to both the Permian and the Mesozoic. It must be the disparity in body forms - only during the mesozoic did reptiles take to the air, become apex predators at sea, and attain sizes unsurpassed by any other terrestrial life.
