/ˈtɛrɔɪd/

Origin: A borrowing from Latin. Etymon: Latin pteroides.

Etymology: < scientific Latin pteroides, adjective (1783 or earlier) < classical Latin pteris fern (see pteris n.) + -oīdēs -oid suffix. With the use as noun compare scientific Latin Pteroides, plural noun (1807 or earlier). N.E.D. (1909) gives the pronunciation as (pt-, te·roid) /pt-, ˈtɛrɔɪd/.

Botany.

A. adj.¹

Having the characteristics of a fern of the genus Pteris or the family Pteridaceae; resembling a fern, filicoid. Cf. pteridoid adj.

1900 B. D. Jackson Gloss. Bot. Terms 215/2 J. Smith uses ‘pteroid’ for Fern-like.

1935 New Phytologist 34 278 Polypodidoid sporangia are commoner in the later deposits than pteroid sporangia.

pteroidadj.²n.¹

Brit.

/ˈtɛrɔɪd/, U.S.

/ˈtɛrɔɪd/

Origin: A borrowing from Greek, combined with an English element; originally modelled on a Latin lexical item. Etymons: Greek πτερόν , -oid suffix.

Etymology: < ancient Greek πτερόν feather, wing (see ptero- comb. form) + -oid suffix, in sense A. 1 after scientific Latin pteroides, adjective (1828 or earlier as a specific epithet in palaeontology). N.E.D. (1909) gives the pronunciation as (pt-, te·roid) /pt-, ˈtɛrɔɪd/.

A. adj.²

1. Chiefly Palaeontology. Esp. of the shell of a bivalve mollusc: resembling a wing. rare.

ΚΠ

1858 R. G. Mayne Expos. Lexicon Med. Sci. (1860) 1038/1 Pteroides, resembling a wing..; pteroid.

1957 Jrnl. Paleontol. 31 761/1 Shell oblique, pteroid, with straight hinge and the slightly projecting beak nearer to the anterior than to the posterior.

1978 Jrnl. Paleontol. 52 1024/2 Small pteroid shells with small anterior and large posterior auricular areas.

2. Palaeontology. Designating various body parts of a pterosaur associated with the small anterior flight membrane, esp. a small, pointed bone that extends from the carpal region towards the shoulder and supports this membrane.

ΚΠ

1882 Amer. Naturalist 16 687 The ‘pteroid bone’ is maintained to be a part of the first digit; it supported a membrane extending from near the shoulder to the wrist.

1957 Jrnl. Paleontol. 31 953/2 Several obscure grooves..may have been made by the trailing edge of the wing or by the pteroid bone as the creature walked unsteadily through the mud.

2004 Nature 2 Dec. 572/1 The presence of the pteroid bone and the long wing-phalanges and wing-metacarpals within the egg shows that JZMP-03-03-2 is an embryonic pterosaur.

B. n.¹

Palaeontology. The pteroid bone of a pterosaur.

ΚΠ

1882 O. C. Marsh in Geol. Mag. 9 209 The ‘lateral carpal’ unites both with the distal carpal and with the ‘pteroid’ by very free, well-defined articulations.

1958 W. E. Swinton Fossil Amphibians & Reptiles (ed. 2) xiii. 97 This is a small splint-like bone known as the pteroid and is not a true first digit.

1996 Proc. Royal Soc. B. 263 45 The origin of the pteroid is unclear: it may be a modified carpal, the first metacarpal, or a neomorph.
