Under the rich Venezuelan soil, paleontologists have found treasures rivaling the bountiful oil: a giant armadillo the size of a Volkswagen, a crocodile bigger than a bus and a saber-toothed tiger.

Oil companies’ soil have uncovered a trove of fossils dating from 14,000 to 370 million years ago.

Many of the 12,000 recorded specimens from different eras are now kept in a tiny office of the Venezuelan Institute for Scientific Research.

A strong smell of oil fills the room as Ascania Rincon opens the drawer of a filing cabinet to reveal the tar-stained femur of a giant, six-tonne mastodon from 25,000 years ago at the end of the Ice Age.

Unfazed by the significance of the finds, the head of the institute’s Laboratory of Paleontology is intent on realizing his next goal: locating human fossils for proof of prehistoric human life in the area.

“We are close. You have to keep exploring the area. We have already found spearheads,” he told reporters. “What’s lacking is reliable indication that man hunted the megafauna that we are finding. And lacking are human fossils.”

Located in northern South America, Venezuela has a complex geological structure that has left it swimming in oil deposits teeming with fossils.

Most of the fossils are concentrated in a large area north of the Orinoco River where the Atlantic Ocean originated 200 million years ago, the paleontologist said.

About 8 million years ago, the Orinoco was formed, followed by the Isthmus of Panama (or Isthmus of Darien, which links North and South America) about 3 million to 5 million years ago.

The fossils found during the surveys include a featherless chicken that looked like an iguana, a 3m pelican and giant sloths that lived on land 12 million year ago, unlike their modern relatives living in the trees.

However, it can take years to prepare a fossil for classification. Experts needed four years to identify a saber-toothed tiger, a darling of the collection dubbed Homotherium venezuelensis.

Once a fossil is found, experts must remove the sediment, transport it, wash it and carefully compare it to existing specimens.

This month, the institute plans to announce the discovery in a remote area of the country of a new species, Rincon said proudly, without revealing the whole surprise.

“Imagine a puzzle of 5,000 pieces and you have 200 pieces you are trying to interpret and draw a conclusion that might contribute something to science,” he said.

Rincon’s laboratory, staffed with only five researchers, has state and private support, but lacks the logistical and technological resources of operations in other countries.

His team finds in paleontology a mission to raise awareness of what was on the planet millions of years ago and encourage people to care for the Earth today.
