The mysterious structure is cone shaped, made of "unhewn basalt cobbles and boulders," and weighs an estimated 60,000 tons, the researchers said. That makes it heavier than most modern-day warships.

Growth cones are the specialized motile structure at the growing tips of developing and regenerating axons and dendrites. They are responsible for directed axon extension, dendritic growth and arborization, and consolidation of the motile tip into the cylindrical axon or dendrite. They were discovered over 100 years ago by Ramon y Cajal who ...Cone-in-cone structures are secondary sedimentary structures that form in association with deeper burial and diagenesis.

Cone beam CT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity and sinuses.Seed Cones. The seed cones are terminal or axillary, cone-like or highly reduced, usually fleshy [rarely dry], in some taxa subtended by a stalk ("peduncle") that may fuse with bracts, forming a fleshy "receptacle," ovuliferous scales 1-∞, each bearing a single ovule, in some members a single scale modified as a protective covering around the ovule, the "epimatium".
