Temporal range: Early Triassic
|Reconstruction of a Conodont|
Hindeodus parvus is an extinct species of conodont whose first appearance in the fossil beds at Meishan, Changxing County, Zhejiang marks the base of the Triassic, and thus the boundary between the Triassic and Permian.
The International Commission on Stratigraphy (ICS) has assigned the First Appearance Datum of Hindeodus parvus as the defining biological marker for the start of the Induan, 252.2 ± 0.5 million years ago, the first stage of the Triassic.
