We survey the known avian fossils from Ypresian (early Eocene) fossil sites of the North American Okanagan Highlands, mainly in British Columbia (Canada). All specimens represent taxa that were pre...

One new genus of Inocelliidae (Raphidioptera) with one new species and one undetermined specimen is described from the Eocene of North America: Paraksenocellia borealis new genus, new species from the early Eocene (Ypresian) Okanagan Highlands shale at Driftwood Canyon, British Columbia, Canada (a forewing), and Paraksenocellia species from the middle Eocene (Lutetian) of the Coal Creek Member of the Kishenehn Formation, northwestern Montana, United States of America (a hind wing). These are the...

Lithochrysa borealis sp. nov. (Neuroptera: Chrysopidae: Nothochrysinae) is described from the early Eocene locality at Driftwood Canyon (British Columbia, Canada). The forewing venation of the new species is similar to that of the late Eocene L. wickhami (Cockerell, 1914) from Florissant (Colorado, U.S.A.), but is distinguished from it by a slightly longer intramedian cell and distinctly longer branches of RP to CuA between the pseudocubitus and the posterior margin.

The Quilchena fossil locality is dated (51.5 ± 0.4 Ma) to the Early Eocene Climatic Optimum, and this locality is reconstructed as the warmest and wettest of the Early Eocene upland sites from the Okanagan Highlands of British Columbia and northern Washington State. Mean annual temperature (MAT) is estimated from leaf margin analysis, using 55 dicot morphotypes, as 16.2 ± 2.1 °C/14.6 ± 4.8 °C. Using bioclimatic analysis of 45 nearest living relatives, a moist mesothermal climate is indicated (MA...

We describe three new genera and four new species (three named) of siricomorph sawflies (Hymenoptera: Symphyta) from the Ypresian (early Eocene) Okanagan Highlands: Pamphiliidae, Ulteramus republicensis new genus, new species from Republic, Washington, United States of America; Siricidae, Ypresiosirex orthosemos new genus, new species from McAbee, British Columbia, Canada; and Cephidae, Cuspilongus cachecreekensis new genus, new species from McAbee and another cephid treated as Cephinae species ...

Stem-group Phasmatodea, known as the Susumanioidea, are previously established from the Jurassic through the Paleocene. Here, we extend this record to the early Eocene with five new fossils: two forewings from the Klondike Mountain Formation exposures at Republic, Washington, United States of America, and three partially complete specimens from the McAbee locality in southern British Columbia, Canada. We assign both of the Republic specimens to the new genus and species Eoprephasma hichensi new ...

Ypresioneura obscura gen. et sp. nov. from the early Eocene (Ypresian) McAbee locality (Canada, British Columbia) is described. It is assigned to the extinct neuropteroid family Corydasialidae, as the second known genus and species. The Corydasialidae was previously known only from late Eocene (Priabonian) Baltic amber. It was originally assigned to the Megaloptera, but the character states that support this conclusion are not strongly diagnostic. There is still doubt as to whether this family b...
