Polacanthusn.

Brit.

/ˌpɒləˈkanθəs/, U.S.

/ˌpɑləˈkænθəs/

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

Etymology: < scientific Latin Polacanthus (attributed to R. Owen (see quots. 1865, 1866); however, neither the use by Owen nor that by Fox has been traced) < ancient Greek πολυ- poly- comb. form + ἄκανθα thorn, spine (see acanthus n.) + scientific Latin -us, after classical Latin masculine nouns in -us (to match the names of other dinosaur genera).

Palaeontology.

A genus of nodosaurid dinosaurs characterized by large bony spines that were probably arranged on both sides of the backbone; (also polacanthus) a dinosaur of this genus.Only known from a partial skeleton from the Wealden of the Isle of Wight, England, and perhaps identical with Hylaeosaurus, from the Wealden of Sussex.

1865 Illustr. London News 16 Sept. 270/1 A very remarkable reptile to which Professor Owen has given the name of Polacanthus has lately been discovered by Rev. W. Fox.

1866 W. Fox in Rep. Brit. Assoc. Advancem. Sci. 1865 56 With reference to the extraordinary nature of the spine-like bones, Professor Owen is of opinion that the most appropriate name for this new Saurian would be Polacanthus.

1892 E. Hutchinson Extinct Monsters vii. 98 It is hoped that..further remains of the Polacanthus will be brought to light.

1948 W. E. Swinton Corridor of Life xii. 162 The presumption is that Polacanthus, as the animal is called, was a heavy, slowly moving vegetarian.

1985 D. Norman Illustr. Encycl. Dinosaurs 161/3 The skeleton of Polacanthus lacks the head and much of the front half of the body..apart from the spines, which were found scattered near the remainder of the fossil.

2002 Times Educ. Suppl. 27 Sept. (Going Places) 14/2 Looking rather like the more familiar stegosaurus, an armoured polacanthus watches from a discreet distance.

This is a new entry (OED Third Edition, September 2006; most recently modified version published online March 2022).
