Pseudomorph from 2024 Western Australia

Western Australian limonite pseudomorph:
This pseudomorph has retained the shape of an original object, but replaced the original minerals with other minerals. Thus the name pseudomorph which means fake shape.
As it likely took a long geologic time to make this transformation, it truly is an antique!
It's my 2024 opinion, not an expert one, that the original form was a pine cone.
