What is "ossifrage"

Lammergeir \Lam"mer*geir\ (l[a^]m"m[~e]r*g[imac]r), Lammergeier \Lam"mer*gei`er\, lammergeyer \lam"mer*gey`er\ (l[a^]m"m[~e]r*g[imac]`[~e]r), n. [G. l["a]mmergeier; lamm, pl. l["a]mmer, lamb + geier vulture.] (Zo["o]l.) A very large vulture ( Gypa["e]tus barbatus), which inhabits the mountains of Southern Europe, Asia, and Northern Africa. When full-grown it is nine or ten feet in extent of wings. It is brownish black above, with the under parts and neck rusty yellow; the forehead and crown white; the sides of the head and beard black. It feeds partly on carrion and partly on small animals, which it kills. It has the habit of carrying tortoises and marrow bones to a great height, and dropping them on stones to obtain the contents, and is therefore called bonebreaker and ossifrage. It is supposed to be the ossifrage of the Bible. Called also bearded vulture and bearded eagle.

"sea-eagle, osprey," c.1600, from Latin ossifraga "vulture," fem. of ossifragus, literally "bone-breaker," from ossifragus (adj.) "bone-breaking," from os (genitive ossis) "bone" (see osseous) + stem of frangere "to break" (see fraction). By this name Pliny meant the lammergeier (from German, literally "lamb-vulture"), a very large Old World vulture that swallows and digests bones and was believed also to drop them from aloft to break them and get at the marrow. But in England and France, the word was transferred to the osprey, perhaps on similarity of sound between the two words.

n. 1 (context obsolete English) The lammergeier. 2 (context obsolete English) The young of the sea eagle or bald eagle.
