Strata of the Mount Mark Formation, Buttle Lake Group, exposed in the vicinity of Marble Peak in Strathcona Provincial Park, central Vancouver Island, contain a diverse Early Permian crinoid fauna. This is the first Permian fauna containing crowns and cups recognized from Wrangellia terrane. The fauna contains representatives of each of the major Paleozoic crinoid subclasses: Camerata, Disparida, and Cladida. Specimens were observed and photographed between 2004 and 2008. No specimens were collected in adherence to regulations of Stratcona Provincial Park. Preliminary identifications recognize several new genera and species within the fauna, but they are not named or described lacking specimens for repository. A minimum of 24 species are judged to be in the fauna, making it the second most diverse Permian fauna known from North America. Identified genera suggest a greater relationship to North American faunas than to Paleotethyan faunas, suggesting Wrangellia was closer to North America than to the Paleotethyan realm during Early Permian time. Exposures of the Mount Mark Formation in the vicinity of Marble Peak are undergoing karstification, and specimens are being lost under the harsh weathering conditions. Observations of individual specimens over a five-year interval found that morphologic details critical for identification are being lost at an alarming rate. It is recommended that sufficient specimens in the fauna should be collected as soon as possible for identification and analysis. These specimens should be preserved for future reference and could form an educational display in the Strathcona Provincial Park headquarters.

The following new species of littoral enchytraeid are described from the east coast of Vancouver Island, British Columbia—Enchytraeus cryptosetosus, Lumbricillus mirabilis, L. vancouverensis, L. georgiensis, L. qualicumensis, L. belli. These descriptions bring the number of North American Enchytraeus spp. to 6 and that of Lumbricillus spp. to 13. Existing evidence suggests that the enchytraeid fauna of the Pacific slope is quite distinct from that of the rest of North America and may have closer affinities with that of the northwest Pacific.

A record of secular variation has been obtained from a stalagmite from Vancouver Island, British Columbia, Canada, covering the period 18.5–15.0 ka BP. The ages, obtained by the U–Th method, were not fully constrained because of the low U content of the sample. The record contributes to a regional type curve obtained from the sediments of Bessette Creek (31–19 ka BP), and to which it shows similar features. In particular, a 1600 year long signal of easterly bias and shallow inclinations is similar to three earlier such features, attributed by M. E. Evans to oscillating geomagnetic sources to the west of North America. The later part of the composite record correlates fairly well with other western North American lake records. There is no evidence for a geomagnetic excursion during this period for the western North American continent.

Geographical Locations

Twenty-five species of Polychaeta recently collected off the coast of British Columbia are discussed. Most were taken in waters of considerable depth off the west coast of Vancouver Island. Sixteen are new to British Columbia. Most of these are known from farther south on the west coast of North America, but some from much shallower depths than those from which they are now recorded; two of them are new to the northeast Pacific; one is a new subspecies. The other nine have been previously known from British Columbia, but they are now recorded from much greater depths than hitherto, or in new geographical locations.

Freshwater Teleosts

Contrary to ideas that Cretaceous fresh waters contained few teleosts, there were several taxa of Esocoidei (pikes and relatives) in North American Cretaceous rivers. Dentaries and palatines of Campanian to Maastrichtian age all have C-shaped tooth bases and other distinctive features of shape and foramina. The fossils include at least three distinct kinds, two of which are described here as new genera and species in the Esocidae: Estesesox foxi n. gen. and sp. and Oldmanesox canadensis n. gen. and sp.These old, diverse, and apparently primitive specimens show that pikes radiated when Eurasia and North America were still joined. Some references in the literature to the Cretaceous fish Platacodon Marsh are based on referred dentaries that are here identified as esocoid fossils. The Esocidae are the first example of a family of Recent North American freshwater teleosts that has been shown to have speciated in Cretaceous fresh waters and survived the terminal Cretaceous extinction.

A new species Bradyidius saanichi from Saanich Inlet, Vancouver Island, British Columbia, Canada, is described and illustrated in detail. This species is closely related to B. pacificus (Brodsky, 1950) among the six previously known species in the genus, but can be readily distinguished from the latter by the strongly divergent rostral rami in addition to some other differences.
