1 Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite. 2  Fossils of T. rex prey, including Triceratops and Edmontosaurus, suggest T. rex crushed and broke bones as it ate, and bone fragments have been found in its dung.
Etiology. Infection is the principal cause of tympanic membrane perforation (TMP). Acute infection of the middle ear may cause a relative ischemia in the drum concurrent with increased pressure in the middle ear space.This leads to a tear or rupture of the eardrum that is usually preceded by severe pain. If the perforation does not heal, it leaves a residual tympanic membrane perforation (TMP).nfection is the principal cause of tympanic membrane perforation (TMP).

The tympanid membrane is the eardrum of the frog. It vibrates and lets the frog know danger is near. The frog will use it's own croak, song, or peep to (echo) bounce sound off â¦ of trees, rocks, sticks or other things and the frog will instantly know if a predator is close if something seems amiss.t sweeps and cleans the eye of debris. It also allows the frog to see clearly under water by shielding the eyes (similar to swimming goggles over one's eyes).
