Definition of "cordate"

If, for instance, the context:(1) Necessarily all cordates are cordatesis available in the language, then the desired contrast seems to work out. […] At the same time, as desired, ‘cordate’ remains interchangeable with ‘creature with a heart’, at least in the example (1); for necessarily all cordates, by definition, have hearts.

1970, Willard Van Orman Quine, Philosophy of Logic, pages 8–9

The organisms in any sample of tigers will almost always happen to exemplify genetic properties more specific than the property shared by exactly the tigers, as well as a number of more inclusive ones such as properties common to all mammals or to all cordates.

2002, Timothy McCarthy, Radical Interpretation and Indeterminacy, page 124

Sciences of cordates — creatures with hearts — are, for example, less general or comprehensive than sciences of living things, and the latter are less comprehensive and general than sciences of moving things.

It is the coextension problem, the problem of the renates and the cordates, the creatures with kidneys and the creatures with hearts.

2012, K. Mulligan, Language, Truth and Ontology, page 16

The upper loam (E) has been reported to have yielded several white-patinated implements, including a large number of pointed handaxes, cordates, ovates and cleavers.

1977, D. K. Bhattacharya, Dibyendu Kanti Bhattacharya, Palaeolithic Europe, page 46

Of the 58 ovates, cordates and cleavers examined, 21 have a tranchet sharpened edge, and 14 are twisted.

1985, John Wymer, The Palaeolithic Sites of East Anglia, page 107

Slightly derived handaxes from the Mildenhall glaciofluvial sands, generally in fresh condition and dominated by ovates and cordates.
