Even the Scotland series probably belongs to the Tertiary system, but owing to the want of characteristic fossils, it is impossible to determine with any degree of certainty the precise homotaxis of the several formations.    From Wordnik.com.  [Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 3 "Banks" to "Bassoon"] Reference

In anatomy, where such correspondence of position has constantly to be spoken of, it is denoted by the word “homology” and its derivatives; and for Geology (which after all is only the anatomy and physiology of the earth) it might be well to invent some single word, such as “homotaxis” (similarity of order), in order to express an essentially similar idea.    From Wordnik.com.  [Essays] Reference
