Oryctocephalus indicus

Oryctocephalus indicus is a type of ancient sea creature called a trilobite that lived during a time called the Cambrian. Trilobites were small, hard-shelled animals that crawled on the ocean floor millions of years ago. Oryctocephalus indicus is special because scientists use it to help mark the start of a specific time period called the Wuliuan, which is part of an even bigger time section known as the Miaolingian.

This trilobite was first found and described in 1910 by a British scientist named Frederick Richard Cowper Reed. He originally called it Zacanthoides indicus. Later, in 1938, another scientist from America named Charles Elmer Resser moved it to a different group called the genus Oryctocephalus, giving it the name we use today.

Studying fossils like Oryctocephalus indicus helps us understand how life on Earth began and changed over millions of years. These tiny, ancient creatures give scientists clues about the conditions of the early oceans and how animals first appeared in the sea.
