The ...Deer incorporate both physical and behavioral adaptations for survival. Physical adaptations are in their fur, senses, antlers, hooves and stomachs. Deer also exhibit behavioral adaptations in communication.The Antler Orogeny caused weak to moderate deformation in the western United States (Fig. 7.4). Parts of the Antler Orogen are now buried by younger deposits, so it is difficult to know its true geographic extent, but from the outcrops that have been identified, the Antler Orogen appears to be about 1/10 the size of the Cordilleran Orogen.An episode of mountain building (the Antler Orogeny) occurred toward the end of the Devonian and continued into the early part of the Carboniferous. By the Permian, sea level had dropped and parts of Nevada were dry land. Plant fossils can be found in rocks formed in shallow lagoons and beaches in the eastern part of the state, while scattered ...Sonoma orogeny. In contrast, an "extensional" Mediterranean- style arc-continent collision, as has been recently proposed for the earlier (middle Paleozoic) Antler orogeny, is probably not an appropriate analogue for the Sonoma orogeny. The weak structural response of the McCloud arc during SonomanAlong North America's eastern margin, this collision is known as the Alleghenian orogeny, which put the final deformational touches on the Appalachian Mountains. Along the southern margin of North America, the Ouachita-Marathon orogeny created a similar chain of folded mountains, now largely eroded away and buried in sediment.The Antler Orogeny continued into Mississippian and Pennsylvanian. Late Paleozoic Orogenies of western North America. A volcanic island arc collided with the ...This may have occurred during two orogenies, the Late-Devonian to Early-Carboniferous Antler Orogeny, and the Late-Jurassic to Early-Tertiary Columbian/Laramide Orogeny.
