This article is a bit of a rehash of other items on the site.
“Reports of strange flying reptiles, some quite large, have continued well into modern times. As we shall see, reports of pteranodons, dragons, thunderbirds, and other similar monsters, are relatively common. Could the sudden rash of Chupacabras attacks and sightings be related to the occasional rash of pteranodon sightings?
Many of the aspects of the Chupacabras and living pteranodons seem to match. They are both monsters and flesh eaters. Pteranodons may well drink blood and gorge themselves on internal organs, which are easy to eat.
Carrion birds such as vultures and condors eat the exposed softer flesh first, lips, eyes, underbelly, etc. It would seem natural for pteranodons to do this as well.”
