Chaco Spine Lizard

Horned lizards, or horny toads, as they are popularly known throughout the West, have long had a particular mystique in American folklore. The ancient peoples of the Southwest, the Anasazi and the Mimbres, depicted the little lizard on pottery and in petroglyphs. In more recent times, it represented health and happiness in the symbology of Native Americans. Among Americans today, the horny toad has an almost legendary appeal. Many westerners remember times when the lizards were plentiful and children kept them on string leashes or in boxes as pets. Dried horned lizards were sold in the roadside curio shops along the nation's major highways. More recently, as the lizards' habitat has shrunk and as imported fire ants have supplanted their favored prey, their numbers have declined drastically In many regions where the little creatures once abounded, they are no longer seen. In Texas, two of the three native species, the Texas horned lizard and the mountain short-horned lizard, are now designated as threatened. Jane Manaster has written this book for a general audience, but she treats all aspects of the lizards' biology as well as the horned lizard's place throughout the culture of the West. Most of all, she has written it to attract attention to this little animal that deserves our respect and protection.

Chaco Canyon in Northwestern New Mexico contains a remarkable set of ancient puebloan ruins. Occupied between AD 850 and 1150, Chaco appears to have been the cultural and political center of a network that extended throughout the Four-Corners region. The Chaco Culture National Historical Park is now a protected site and has been continuously studied for a century. R. Gwinn Vivian and Bruce Hilpert have written an encyclopedic handbook to help organize the extensive amount of information available for Chaco, as well as to stimulate speculation and encourage further exploration. The result is a highly accessible but thorough reference. The Chaco Handbook includes over 250 cross-referenced, alphabetical entries, 100 figures and illustrations, plus histories of Chaco's development and archaeological research. Entries address important Chacoan and related sites, place-names, archaeological and ethnographic terms, objects and architectural features, and institutions and individuals. The utility of this fascinating handbook extends well beyond the immediate vicinity of the Park, for it will be useful to anyone with an interest in the ancient puebloans, including specialists. Whether used during a trip to Chaco, following visits to Chacoan places, or as a quick reference for dates and definitions, The Chaco Handbook will guide readers to greater exploration of Chacoan culture and the Chaco world.

Spinosaurus - Spinosaurus aegyptiacus ("Egyptian spine lizard") is a theropod dinosaur species from the Albian to early Cenomanian stages of the Cretaceous period, about 95 to 93 million years ago.

Mountain Short-Horned Lizard - The mountain short-horned lizard, also called Hernandez's short-horned lizard or the greater short-horned lizard, (Phrynosoma hernadesi) is a diurnal species of phrynosomatid lizard. It is an insectivore, feeding mostly on ants, though will also eat young snakes.

Spine lock - A spine lock (also known as a spine crank, and technically known as a spinal lock) is a multiple joint lock applied to the thoracic or lumbar regions of the spine, causing hyperflexion or hyperrotation by twisting or bending the upper body beyond its normal ranges of motion. A spine lock might result in a spinal muscle strain, and if applied forcefully and/or suddenly, may cause serious spinal injury such as damage to the intervertebral discs, joints, ligaments and nerve ...
