Originating from the Upper Jurassic era, precisely dating back to 154 million years ago, the genuine skeletal remains of a Camptosaurus represent a singular specimen discovered in Albany County, Wyoming, USA. This prehistoric relic spans a length of 3.76 meters (12.34 feet), stands at a height of 1.40 meters (4.6 feet), and measures 0.94 meters in width (3 feet). The cranial region of the Camptosaurus, initially measuring approximately 25 centimeters (9.8 inches), housed a brain estimated to have ranged between 6 to 8 centimeters (2.3 to 3.1 inches) in dimension.

Remarkably, a meteorite of precisely analogous dimensions has been positioned atop the cervical structure of the skeleton, symbolically denoting the site of the dinosaur's cerebrum. In a poignant connection to history, it is notable that 65 million years ago, meteoritic impact events, prominently exemplified by the Chicxulub impactor—an asteroid or comet of significant proportions measuring 11 to 81 kilometers (6.8 to 50.3 miles) in diameter—materialized as a principal catalyst in the mass extinction of dinosaurs. The meteorite's configuration, reminiscent of the human brain, has been thoughtfully oriented, with the brainstem positioned to the left, extending towards the neck, while the larger frontal region of the brain occupies the rightward position.

The installation's evocative title, 'Where's your head at,' serves as a contextual anchor for contemplating facets of mental equilibrium or rationality, perceptibly alluding to the potential erosion of sanity or sound judgment. This metaphor extends as a potent allegory beseeching humanity's adept management of Earth and its interconnectedness with the cosmos over extended temporal horizons. Profoundly underscored by the ongoing challenges posed by extreme climatic variations, anthropogenic environmental degradation, and catastrophic natural events, the installation reverberates as a resonant call to action against these looming existential threats.

It is prudent to recognize that our human species, while often inclined towards an enduring perspective, is but one facet of a broader narrative within the tapestry of life on Earth. The dominance of dinosaurs during epochs long past stands as a humbling testament to the transient nature of dominion. Within this dynamic, the capacity for intellect and cognitive prowess emerges as the hallmark differentiator, setting humanity apart from other inhabitants of the planet. In light of this unique endowment, the installation implores us to harness our cognitive faculties to their utmost potential, avoiding the descent into mental stagnation or indifference.

In finality, 'The Authentic Camptosaurus Skeleton' installation serves as a poignant confluence of scientific heritage, symbolic allusion, and a compelling plea for responsible stewardship of our planet. By contemplatively engaging with the meteorite-crowned remains of an ancient creature, viewers are prompted to reflect upon the trajectory of life and the collective imperative to galvanize intellectual acumen for the preservation of our world, lest our cerebral faculties languish in an arid mental expanse.
