AN ISLE of Wight fossil collector has made another spectacular discovery – a huge, rare ammonite.

Wight Coast Fossils guide Jack Wonfor recovered an Epicheloniceras ammonite from a fallen block from the Lower Greensand on the Island's southwest coast.

“It's actually so big, it maxed out the scales,” said a spokesperson for the group.

“A good 150kg or more.

“After many hours, extracting it from the boulder, it took several attempts to recover it from the beach due to its size and weight.”

The team had to rebury it three times and lost a rucksack along the way.

It’s far from Jack’s first find, but is perhaps among his best.

Back in March, he discovered a huge 10,000-year-old Ice Age horse skull washed up on an Island beach.

“It's definitely the biggest ammonite Jack has ever recovered,” said a spokesperson for the group.

“We're all super happy to have it off the beach safely and saved from the destruction of the sea.

“This ammonite recovery wouldn't have been possible without the help of friends and fellow fossil collectors all coming together.

“Thanks to Glenn Martin for lending Jack his tools to extract the ammonite in the first place, and to Scott Cade, Meg Jacobs, Andy Jacobs, Paul Berry, Isaacs Roberts and Miles Taylor.

“Jack is especially grateful to James Blake, who spent all afternoon dragging, lifting and hauling this ammonite back to the car.”
