fossilization

A team of researchers has developed an innovative method based on fossilization processes to seal cracks and fractures in rock using a "concretion-forming resin."

Nawrot studies changes in marine ecosystems that have occurred since the last ice age, a field in which knowing the various factors that help or hinder fossilization is critical.

Given the rarity of fossilization for hominin remains and how few have been found, we might never catch a glimpse of our immediate direct ancestor, Wood says.

To help interpret the chemical signals preserved in the fossil feathers, the team also ran experiments to help understand how feather proteins break down during the fossilization process.

Unlike other methods of fossilization in which organic matter is replaced over time by sediment, tar preserves a bone’s collagen, which is more conducive to getting a precise radiocarbon date.
