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.

Early Eocene fossil floras from British Columbia are a rich resource for reconstructing western North American early Cenozoic climate. The best known of these floras reflect cooler (MAT ≤ 15 °C) upland forest communities in contrast to coeval (MAT ≥ 18 °C) forests in lowland western North American sites. Of particular interest is whether Early Eocene climates were monsoonal (highly seasonal precipitation). The McAbee site is a 52.9 ± 0.83 Ma 0.5 km outcrop of bedded lacustrine shale interbedded with volcanic ash. In this report two historical megaflora collections that were collected independently from different stratigraphic levels and (or) laterally separated by ∼100–200 m in the 1980s (University of Saskatchewan) and 2000s (Brandon University) are investigated to (i) assess whether they represent the same leaf population, (ii) assess whether a combined collection yields more precise climate estimates, and (iii) reconstruct paleoclimate to assess the character of regional Early Eocene precipitation seasonality. Combined, the two samples yielded 43 dicot leaf morphotypes. Analysis of leaf size distribution using ANOVA showed no difference between the two samples, and thus they were combined for climate analysis. Climate analysis using leaf physiognomy agrees with previous estimates for McAbee and other regional megafloras, indicating a warm (MAT ∼8–13 °C), mild (CMMT ∼5 °C), moist (MAP > 100 cm/year) ever-wet, non-monsoonal climate. Additionally, we recommend that climate analyses derived from leaf fossils should be based on samples collected within a stratigraphically constrained quarry area to capture a snapshot of climate in time rather than time-averaged estimates derived from multiple quarry sites representing different stratigraphic levels within a fossil site.

A well-preserved molar of a woolly mammoth (Mammuthus primigenius) was recovered from deposits at Chestermere Lake near Calgary. It is probably of late Wisconsin age, and is one of several mammoth fossils collected from Pleistocene sediments in the Calgary area.The Chestermere Lake specimen is considered in relation to 94 records of mammoth cheek teeth from the western Canadian provinces. Of the 94 records, 5 are from Manitoba, 35 are from Saskatchewan, 37 are from Alberta, and 17 are from British Columbia. In addition to specimens of woolly mammoths, remains of Columbian (Mammuthus columbi), imperial (Mammuthus imperator), and southern mammoths (Mammuthus meridionalis) have been collected from Pleistocene deposits of southwestern Canada. Some problems concerning the relationships of North American and Eurasian mammoths are mentioned.

New ammonite faunas are described from sections along Bighorn and Scalp creeks in central-western Alberta where Lower Jurassic parts of the Fernie Formation are exposed. The first record of the upper Sinemurian Obtusum Zone from the Fernie is based on the occurrence of Asteroceras cf. stellare and Epophioceras cf. breoni in the basal pebbly coquina on Bighorn Creek. The overlying Red Deer Member has yielded Amaltheus cf. stokesi, representing the upper Pliensbachian Margaritatus Zone; in immediately superjacent strata the first North American examples of ?Amauroceras occur together with Protogrammoceras and ?Aveyroniceras. In the basal parts of the overlying Poker Chip Shale a fauna including Harpoceras cf. falciferum, Harpoceratoides, Polyplectus cf. subplanatus, Hildaites cf. serpentiniformis, and Dactylioceras cf. athleticum is correlated with the lower Toarcian Falciferum Zone.The upper parts of the Poker Chip Shale on Fording River in southeastern British Columbia contain a fauna representing some part of the upper Toarcian, but owing to poor preservation, generic identifications are only tentatively made.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

When we arrived in Vancouver at the start of our vacation, the tabloid headline at the newspaper stand caught our attention. “World’s Bravest Mom,” it shrieked. We stopped to read. The story was simple; it needed no journalistic embellishment. Dusk, August 19, 1996. Mrs. Cindy Parolin is horseback riding with her four children in Tulameen, in southern British Columbia’s Okanagan region. Without warning, a cougar springs out of the vegetation, hurtling at the neck of one of the horses. In the confusion, Steven Parolin, age six, falls off his horse and is seized by the cougar. Mrs. Parolin, armed only with a riding crop, jumps off her horse and challenges the cougar, which drops the bleeding child and springs at her. Ordering her other children to take their wounded brother and go for help, Mrs. Parolin confronts the cougar alone. By the time rescuers reach her an hour later, she is dying. The cat, shot soon afterward, was a small one, little more than sixty pounds. Adult male cougars can weigh as much as 200 pounds, we learn the next day from the BC Environment’s pamphlet entitled “Safety Guide to Cougars.” We are on our way to Garibaldi Provincial Park, where we plan to do some hiking, and have stopped in the park head-quarters for information. “Most British Columbians live all their lives without a glimpse of a cougar, much less a confrontation with one,” says the pamphlet, noting that five people have been killed by cougars in British Columbia in the past hundred years. (Actually, the number is now higher; cougar attacks have become increasingly common in the western United States and Canada in recent years.) “Seeing a cougar should be an exciting and rewarding experience, with both you and the cougar coming away unharmed.”However, the pamphlet notes, cougars seem to be attracted to children as prey, possibly because of “their high-pitched voices, small size, and erratic movements.” When hiking, “make enough noise to prevent surprising a cougar . . . carry a sturdy walking stick to be used as a weapon if necessary,” and “keep children close-at-hand and under control.”
