California has always been the favorite place of bone boffins. The western US state has delighted them with eyebrow raising fossils a number of times. Once again, the region provided bone boffins some ancient fossils. Scientists discovered 5,000 to 10 million years old fossils on public beach in Santa Cruz County, California.

Marine biologist Giancarlo Thomae was the person who found an ancient megalodon tooth on the beach. The tooth could belong to a 60-foot great white shark. Earlier, the biologist found a tooth of a great white shark which was estimated to be around 4 million-year-old. Apart from that, some workers in Carlsbad discovered Ice Age fossils of mammoth that could be 200,000 years old.

The earliest discovered fossils represent microbial life forms and could be of the animal living during Proterozoic times, when western North America was covered with waters. About four years ago, some workers discovered nine whale skulls when they were working on a project. Paleontologist Jim Walker and some construction crew members unearthed about 529 types of fossils. About 168 of them were vertebrates like sharks, while 267 belonged to invertebrates.

According to Jim, "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."

Tom Demere, the curator of palaeontology at the San Diego Museum of Natural History said the fossils were found in July this year, and there are possibilities that the site has more fossils of this type.
