The name, Terebratula, may be derived from the Latin "terebra", meaning "hole-borer". The perceived resemblance of terebratulid shells to ancient Roman oil lamps ... Nature Picture Library offers the best nature photographs and footage from the world's finest photographers, to license for commercial and creative use.Lingulata shells are composed of a combination of calcium phosphate, protein and chitin. This is unlike most other shelled marine animals, whose shells are made of calcium carbonate. The Lingulata are inarticulate brachiopods, so named for the simplicity of their hinge mechanism. This mechanism lacks teeth and is held together only by a complex ...Lingulida are free-living brachiopods that burrow in soft substrates; their pedicle does not tether them to a hard substrate. Strophic and astrophic: These are two end-member types of valve hinge lines. Strophic hinges are straight (Figure 6a–c,e). Astrophic hinges are curved (Figures 1a and 6d,f). www.annualreviews.org • The Evolution of ...

Mor-ton (1960, p. 117) reviewed all the available knowledge including unpublished material of Atkins on the digestion of brachiopods.

The Lingulidae (Lingulida: Linguloidea) are inarticulate brachiopods that live in a vertical burrow in intertidal to subtidal soft sediments (Peng et al., 2007). Lingulids are well known for their morphological conservatism, exhibiting limited morphological change since the early Paleozoic.The desert is an ecosystem that’s far more diverse than most people realize.

My contribution to this short course is a commentary on and addendum to this review. Brachiopods are (perhaps all too) familiar to any geology student who has taken an invertebrate paleontology course; they may well be less familiar to biology students. Even though brachiopods are among the most significant components of the marine fossil record by virtue of their considerable diversity, abundance, and long evolutionary history, fewer than 500 species are extant.
