The Bradgate Formation is a geologic formation in Leicestershire, and lies within the wider Bradgate Park area. It preserves fossils dating back to the Lower Ediacaran period.

Paleobiota

The Bradgate Formation contains the richest fossil beds within the Charnian Supergroup, from frondose organisms like Bradgatia and Charnia, which when the latter was discovered, showed definitive proof that macroscopic life did indeed exist before the Cambrian,^[3] to discoid forms like Aspidella.
