Besides taking a photo of the Beardmore sword, my other purpose in visiting the Royal Ontario Museum last Sunday was to see their Cambrian fossils. These are dominated by the OG Burgess Shale fossils (including some collected by Charles Walcott himself) and the newer Mistaken Point lagerstätte in Newfoundland.

These are three of personal favourite Hallucigenia. Each is a couple of centimeters long (#3 is actually #2 through a low-power microscope, hence the inversion).

"In 2026, a new Cambrian Lagerstätte entered the scene. Paleontologists in southern China uncovered a trove of some of the best-preserved Cambrian fossils to date — a massive collection of 8,681 fossils spanning 153 species — named the Huayuan biota. Many of the Huayuan fossils look similar, if not identical, to those in the Burgess Shale, indicating that these marine ecosystems were connected by global ocean currents.""

A Treasure Trove of Cambrian Fossils Rewrites the Story of Early Life | Quanta Magazine

Remarkably preserved fossils found in southern China offer a fascinating window into what life looked like at the end of the Cambrian explosion, with half of the species uncovered being new to science.

The dawn of the #Phanerozoic: A transitional fauna from the late #Ediacaran of Southwest China https://www.science.org/doi/10.1126/science.adu2291

"A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the #Cambrian Period."

"Most striking of all, we found the oldest #evidence for the group to which we #humans belong: the deuterostomes. Several of these specimens have a stalk & tentacles, & closely resemble a group of #Cambrian #fossils called cambroernids. These now-extinct #animals are related to living starfish & acorn worms - the closest #invertebrate relatives to humans." See: https://en.wikipedia.org/wiki/Deuterostome.
Humans’ closest invertebrate ancestors date back much further than thought – how we discovered the fossils that show this

Did Earth’s major diversification event really happen in one sudden explosion? Our fossil discovery suggests not.
