Research at the
Denman Institute for Research on Trilobites

Brian Chatterton (University of Alberta) and Rolf Ludvigsen

We have started a major research project on the abundant Lower Silurian trilobites of Anticosti Island, Quebec, Canada. The trilobites of Anticosti are arguably the best preserved Silurian trilobites in North America. Only the phacopid Acernaspis has been revised in recent years. The manuscript should be finished by the end of 2000 and then it will be submitted to Palaeontographica Canadiana.

We are continuing our work on Upper Cambrian trilobites in limestone boulders of the Cow Head Group, western Newfoundland in the C.H. Kindle Collection kept at the Geological Survey of Canada. Presently, we are concentrating on those of Marjuman age. The next paper deals with the peculiar trilobite Hysteropleura.

The first trilobites discovered on Vancouver Island are of Late Carboniferous age and belong to Paladin and Brachymetopus.

I am working on the section on the superfamily Remopleuridacea for volume 3 of the revised Treatise on Invertebrate Paleontology, Part O, Arthropoda 1, Trilobita, Revised. And also on the section on the superfamily Dikelocephalacea (with Steve Westrop and John Shergold). I am also working (slowly) on some Middle Cambrian trilobites of the Avalon Peninsula in Newfoundland.  The photos below are cephala from Kelligrews Quarry.
