Briefings

A 2026 study suggests that early animals were preserved as fossils due to a specific microbial activity, whereas later soft-bodied creatures vanished from the fossil record. The evidence indicates that collagen-eating microbes may have acted as a preservation mechanism for early life forms, while later soft-bodied organisms lacked this protective mechanism. This hypothesis explains why some ancient animals are found while others are not, offering a new explanation for the fossil record gaps.

Key points

• Researchers propose that early animals were preserved as fossils because of a specific microbial activity that acted as a preservation mechanism.

Context and limitations

The evidence is from a 2026 study and relies on researchers' interpretations of microbial interactions with early life forms. The exact mechanism of preservation and the specific microbial agents remain to be fully confirmed.
