Abstract
The putative stem mammal taxon Tikitherium copei was erected based on a single tooth, identified as an upper molar, from the Upper Triassic Tiki Formation of India. Originally thought to be Carnian in age, this taxon was regarded as the oldest mammaliaform in the fossil record. We show that this tooth actually represents the last upper premolar (P4) of a Neogene crocidurine soricid insectivore (order Lipotyphla).
期刊介绍：
Journal of Mammalian Evolution is a multidisciplinary forum devoted to studies on the comparative morphology, molecular biology, paleobiology, genetics, developmental and reproductive biology, biogeography, systematics, ethology and ecology, and population dynamics of mammals and the ways that these diverse data can be analyzed for the reconstruction of mammalian evolution. The journal publishes high-quality peer-reviewed original articles and reviews derived from both laboratory and field studies. The journal serves as an international forum to facilitate communication among researchers in the multiple fields that contribute to our understanding of mammalian evolutionary biology.
