''Kirktonecta'' is an extinct genus of microsaur known from the Carboniferous of West Lothian, Scotland. ==Discovery== ''Kirktonecta'' is known from the holotype specimen UMZC 2002, a and b, an almost complete skeleton including the skull, and preserved evidence for soft tissues, in part (slab a) and counterpart (slab b). The holotype was collected in the East Kirkton Quarry, near Bathgate of West Lothian, from "Bed 82" East Kirkton Limestone of the Bathgate Hills Volcanic Formation, dating to the Brigantian substage, of the late Viséan stage, of the Dinantian series (Early Carboniferous), about 333-328.3 million years ago. It represents the first microsaur to be discovered in the United Kingdom and the earliest occurrence of a microsaur in the fossil record. The next oldest being ''Utaherpeton'' and an unnamed taxon from the Chesterian of Goreville, Illinois.〔
