Fossilized dinosaur proteins and burnt toast share similar chemical compounds. Scientists say under the right conditions, soft tissue from dinosaurs can be fossilized and during that process the tissue experiences chemical transformations which are similar to those that burnt toast experiences. Research has found that soft tissue found in places such as sandstone and shallow marine limestones is more resistant to decay. Paleontologists note that the tissue found in that environment is structurally similar to compounds that form on the outer layers of burnt toast. These findings, published in the journal Nature Communications, could help paleontologists know where to look for preserved soft tissue.
