	Equisetum Similkamense ''Equisetum similkamense'' is an extinct horsetail species in the family Equisetaceae described from a group of whole plant fossils including rhizomes, stems, and leaves. The species is known from Ypresian sediments exposed in British Columbia, Canada. It is one of several extinct species placed in the living genus ''Equisetum''. History and classification Fossils of ''Equisetum similkamense'' were collected during field work in 1877 from outcrops of the Allenby Formation along Nine Mile Creek near Princeton. These were examined and described by John William Dawson (1879) as a new species based on stems, leaves, and rhizomes. Dawson did not give an etymology for the species name in the type description, though the type locality of Nine Mile Creek is a tributary of Whipsaw Creek, a tributary in turn of the Similkameen River. Dawson (1890) reprinted his description of the species with some elaboration of the details and included drawn illustrations of representative fossils. Daw ...

picture info	Water Strider The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, or water skimmers. Consistent with the classification of the Gerridae as true bugs (i.e., suborder Heteroptera), gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals. They are anatomically built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake. Over 1,700 species of gerrids have been described, 10% of them being marine. While 90% of the Gerridae are freshwater bugs, the oceanic '' Halobates'' makes the family quite exceptional among insects. The genus ''Halobates'' was first heavily studied between 1822 and 1883 when Buchanan-White collected several different species during the C ...
