So today I was excited when this book came in. It is not in print anymore and I was lucky I managed to order this copy. It talks about the gastropods, cephalopods, and vermes of the Georgian Bay formation of Toronto, Ontario.image.thumb.jpg.79c94fcec96b802466e96c58e5c51adc.jpg

It even has some nice detailed plates of what can be found in the formation.

I never even knew vermes (worms?)image.thumb.jpg.cc04a308398e67f71541dc81dd78229e.jpg can be found in the formation.

Good score...

Vermes would be 'worms' - I've seen 'Vermiforms' in old publications, meaning any/all of the worm-like taxa collectively (now many phyla).

I expect at least some of the "Vermes" to be conodonts

Those real Vermes present would/could/should  be scolecodonts.

Below(from Eriksson (2015)et al on polychaete jaws from the Eramosa lagerstatt) 

I'd go so far as to say that in the plate figured,21 to 27 are conodonts

Nice aquisition. Sometimes those antiques are the best, although the taxonomy is often somewhat outdated. "Vermes", or Polychaeta, go back as far as the Cambrian. Scolecodonts belong to that class. It is assumed today that conodonts belong to the chordata.

the conodonts look like the usual Georgian Bay suspects

underneath: GB section with conodont distribution

anybody interested in the same for other section(Karawog,e.g.?)
