New Burgess Shale find: Maybe the Cambrian (discovery) Era is just beginning

Spread the love
Marble Canyon Provincial Park, BC, Canada

Further to “New big fossil find in Canada’s Burgess Shale area features internal organs,” some interesting featuress from the Nature Communications paper.:

The soft-bodied fossil assemblage is noteworthy for its high proportion of new taxa—which is surprising considering the locality’s close geographical and temporal proximity to the Walcott Quarry—and also for the preservation of previously unknown or unreported anatomical features, and for the presence of taxa previously only known from the early Cambrian of China.

Which is to say that new life forms that challenge prevailing ideas could in fact be right under our noses in what we think are pretty well tapped out areas.

And ones we think must have been dominant may not have been.

Patterns in fossil associations point to the recurrence of a similar community-type across the fossil-rich interval (Supplementary Data 1). While this suggests that relatively consistent taphonomic, ecological and environmental conditions prevailed throughout the studied interval, it also highlights important differences in content between Marble Canyon and other Cambrian soft-bodied assemblages elsewhere. Sessile organisms, in particular sponges and brachiopods, which are especially abundant and diverse at the Walcott Quarry5 and Chengjiang28 (and to a lesser extent at Stanley Glacier10), are consistently rare at Marble Canyon.

This is a time for discovery not dogmatism about what it means.

    Kinda lazy right now to research it… but what does this find do with timeline Meyer dealt with in his book? Does it tighten the window of time for the camb’explosion?

    Here’s your answer :

    “All of the animals, including the new ones, fit into existing Cambrian phyla,” explains Dr. Meyer. “No transitional intermediates have been discovered.”

    “What’s important to understand is how suddenly, in geological terms, the new body plans emerge,” said Casey Luskin, research director at Discovery Institute’s Center for Science & Culture. “Even if you were to take the most generous evolutionary estimate for the length of the Cambrian explosion, it would not allow enough time for natural selection and random mutations to do the job.”
