Canadian Anomalocarid Appendage

This image is of an anomalocarid appendage (approximately 59 mm in length) found in southeastern British Columbia, Canada. It is from the Lower Cambrian Period and was found in the Eager Formation. This could be a Laggania [NOTE: The multiple long, thin spines which differ from the single, sturdier points of the Anomalocaris].

Thanks again to Howard from Calgary, Canada for today's picture and fossil information.

Howard also notes that the "typical" Anomalocaris with the single, shorter points also occurs in the same formation.

how old is the fossil?

I believe the Lower Cambrian is 542 to 511 million years ago. So that is quite an old fossil!
