Tyrannosaurus Rex: The Early Years. Some of the first, fragmentary fossils of Tyrannosaurus Rex were discovered by the famous paleontologist Edward Drinker Cope (with Othniel. C. Marsh, one of the participants in the notorious 19th-century Bone Wars) in South Dakota in 1892.
Wet behind the ears. Naive. The allusion is to the inexperience of a baby, so recently born as to be still wet. This phrase was in circulation in the USA in the early 20th century - twenty years before it was first recorded elsewhere. The converse of the phrase - 'dry back of the ears', was also known in the USA from around the same date.

is inherited. The wet wax is common in western Europe and contains about 50% fat. Dry wax is common in Asia and contains about 20% wax. How does earwax get out? Your jaw joint forms one third of the ear canal. As you chew or talk, the joint moves the skin of the canal, slowly pushing the wax out and taking trapped debris with it. This wax falls out at random. So it is natural and expected to have flakes of ear wax drop out of your ear canal. Why does wax build up? Earwax is necessary and good. It can build up though blocking the ear canal and causing hearing loss, infection or pain.
