Origin: A borrowing from Greek, combined with an English element. Etymons: Greek πριον- , πρίων , -odont comb. form.

Etymology: < ancient Greek πριον-, πρίων a saw (see prion n.¹) + -odont comb. form. In sense A. 2 after scientific Latin Prionodon, genus name ( T. Horsfield Zool. Researches Java (1824) Mangusta Javanica 13), Prionodontidae, family name (page 11 in the same section of the same work). Compare priodont adj.

A. adj.

1. Zoology. In the shell of a bivalve: designating a type of hinge in which a series of teeth on one valve are inserted into a corresponding series of sockets in the other.

ΚΠ

1889 W. H. Dall in Amer. Jrnl. Sci. 38 452 There can be but three fundamental types of hinges, which may be called the anodont, prionodont and orthodont.

1950 Jrnl. Paleontol. 24 89/2 Many paleontologists and conchologists have made comparisons between the morphology of the Glycymeridae and that of other prionodont pelecypods.

1977 Jrnl. Paleontol. 51 944/1 The prionodont hinge line is long, and the ventral margin of the right valve is sharply incurved.

†2. Zoology. Resembling or belonging to the genus Prionodon or the subfamily Prionodontinae, which comprise the linsangs. Obsolete. rare.Apparently only attested in dictionaries or glossaries.

ΚΠ

1890 Cent. Dict. Prionodont, having the tubercular molars reduced to one on each side above and below, as a civet-cat of the genus Prionodon.

a. Zoology. Having small, closely set teeth; belonging to the armadillo genus Priodontes. Cf. priodont adj. 1. rare. Now disused.

ΚΠ

1890 Cent. Dict. Prionodont, having teeth set like a saw; having serrated teeth.

1908 N.E.D. Prionodont,..a prionodont armadillo, a kabalassou.

b. Entomology. = priodont adj. 2. rare.

1932 J. S. Huxley Probl. Relative Growth vii. 209 A specimen is classified as Amphiodont if a gap is present which is considered larger than the normal gap between two teeth, Prionodont if it is considered not to exceed this size.

1940 G. R. Beer in J. S. Huxley New Systematics 381 The mandibles of the males not only vary in relative size, but also in the number of ‘teeth’ carried on them, to such an extent that five types (‘prionodont’, ‘amphiodont’, ‘telodont’, ‘mesodont’, ‘mesamphiodont’) have been distinguished by coleopterists.

B. n. Zoology.

†1. The giant armadillo, Priodontes maximus. Obsolete. rare.Apparently only attested in dictionaries or glossaries.

1950 Jrnl. Paleontol. 24 89/1 The prionodonts are not closely related to the true taxodonts such as Nucula, Nuculana, and Yoldia.

2001 Jrnl. Paleontol. 75 1119/1 The prionodonts..were intermediate between the anomalodesmatans and the advanced teleodesmaceans with heterodont dentition.
