Origin: Formed within English, by compounding. Etymons: palaeo- comb. form, thermometer n.

Etymology: < palaeo- comb. form + thermometer n.

Geology.

Any geological fact, measurement, or sample that may be used as a means of inferring palaeotemperatures, esp. the relative abundance of the isotopes of certain chemical elements in fossil organic matter.

1989 S. H. Schneider Global Warming (1990) 309 There are a number of complications in the interpretation of O¹⁸ as a palaeothermometer; we have to consider the temperature at which the water evaporated, the temperature at which it precipitated, and its transport path.

2000 Science (Nexis) 10 Nov. 1134 The presence of Mg⁺⁺ in calcium carbonate biominerals is increasingly being used as an empirical paleothermometer.
