Google is celebrating the 374th birthday of Danish anatomist Nicolas Steno with a colourful nod to his offerings to the world of geology. 

Steno is seen as the original modern day geologist, working heavily on fossils and rock layer formations. He was also known for his devotion to Catholicism which has led to mention questioning whether he should be canonised. 

Leaving Copenhagen in 1660 he eventually ended up in Italy where he joined a group of researchers who would follow a similar mathematical scientific method as Galileo 

His main claim to fame is something known as Steno's law of superposition, which essentially explains how layers of rock are arranged in a time position. 

Clicking the Google Doodle does the usual search, bringing up his Wiki page as top. Those who want to find out more about Steno can do so here
