Scientists have discovered fossils that are 5,000 to 10 million years old, at a public beach in Santa Cruz County, California, NYC Today reports.

The marine biologist Giancarlo Thomae discovered the ancient megalodon tooth on a public beach. Experts say that the discovered tooth could belong to a 60-foot long great white shark.

In the last few years, California has delighted archeologists by turning up rare fossils a number of times at different sites.

Earlier, Giancarlo Thomae had also discovered the tooth of a great white shark that was estimated to be around 4 million years old.

Recently, construction workers in Carlsburg discovered Ice Age fossils of a mammoth that could be around 200,000 years old.The fossils, including the bison, only second ever discovered in San Diego County, are from the Pleistocene Epoch, and are between 50,000 and 200,000 years old, Tech Times reports. 

Paleontologist Jim Walker and some construction members discovered around 529 types of fossils, out of which about 168 of the fossils were of vertebrates like sharks, while 267 kinds of fossils belonged to the invertebrates.

According to NYC Times, Jim Walker said,

"We started finding fossils here before construction even started. It was exciting. We were finding scallops, and I said, 'I want to get a whale.' And we did."
