Kogelvormige steen met afdruk schelp Possibly 230000000

This spherical stone with a shell imprint, housed in the Rijksmuseum, is a fascinating example of a natural artifact from the prehistoric period. Dating back to the late Triassic or early Jurassic, approximately 230 million years ago, this object exemplifies the powerful forces of nature and the enduring legacy of ancient life. The imprint, likely from a bivalve mollusk, is a testament to the rich biodiversity that existed long before human civilization. The stone’s natural shape and the shell’s impression, combined with its immense age, make this object a compelling and intriguing artifact of natural history.
