Our Nahanni is a little more benign, but still concerned with the dead sublimely beautiful glassy corpses of trilobites Collage of silicified trilobites etched out of limestone of the Esbataottine Formation using hydrochloric acid. These trilobites come from a single collection in Nahanni National Park. Twenty-one species are shown here. Photo by RL (c). The South Nahanni River arises near the Yukon border, flows past hot springs, cascades over Virginia Falls through the deepest canyons in Canada cut into fossil-bearing rocks that are painted in vivid pastels of bright red and orange. This is the river that justified the establishment of the Nahanni National Park in the Mackenzie Mountains and the designation of a World Heritage Site by UNESCO. It is also a river of myth fuelled by fevered stories about the corpses of Willie and Frank McLeod found in the valley in 1908, robbed of their gold, lashed to trees and missing their heads. The legend is seemingly corroborated by a set of sinister place names for features along the Nahanni Headless Range, Deadmen's Valley, Funeral Range, Broken Skull River, and Hell's Gate.

The CPR hoped that tourists would flock to the West to commune with the mountains. Siltstone slab with moults of the trilobite Ogygopsis klotzi from the Trilobite Beds on Mount Stephen. Tyrrell Museum specimen. Photo by BDEC (c). These trilobites from Mount Stephen are truly spectacular. Virtually every slab on this mountainside boasts complete trilobites some are gleaming black and stand out sharply against the buff-coloured siltstone; others are evident by being slightly raised from the matrix in bas-relief. Ogygopsis is, by far, the most common fossil in the Trilobite Beds. This trilobite has the size and outline of a child's shoe-print and it possesses an uncommonly large tail for a Cambrian trilobite.

Trilobite Reproduction and Development Last revised 02 August 2005 by S. M. Gon III Trilobites are thought to have reproduced sexually , as do nearly all arthropods today. Eggs were presumably laid, but fossilized eggs that may be of Cambrian eodiscid trilobites have been documented only once (Zhang and Pratt 1994). It has recently been suggested that some trilobites may have held eggs and/or developing young within the cephalon (as horseshoe crabs do today), and anterior median swellings of the cephalon (of the preglabellar field) in some specimens are interpreted as brood pouches e.g., Brood Pouches in Trilobites J. Paleontol. 72 Left : dorsal view of cephalon of adult holaspid; preglabellar field is marked "X" and brood pouch swelling is colored (lower left). Right : side view of non-brooding specimen (top), brooding animal (middle) and close-up cut-away showing developing eggs within pouch. Above photo of specimen showing brood pouch The embryology of trilobites is unknown, but after hatching and development of a hard exoskeleton (which presumably occurred soon after hatching) they molted their exoskeletons as they grew, as all arthropods today, leaving a record of their developmental stages. Thus, the
