Abstract
This paper examines the Dinosaurs of the Jurassic Period. The paper considers the holistic view of the Jurassic period in addition to the Dinosaurs that roamed the Earth during this period. Finally, historical consideration evidence leading to the demise or disappearance of the dinosaurs. Analysis is based upon research conducted from ten academic reference sites. The paper provides an understanding of the different species that lived during the Jurassic period and the environmental and climatic conditions that supported them. Also discussed is a significant amount of information regarding palaeontologists’ discoveries of great dinosaur faunas, such as the

Thus, oceans engulfed the areas in between, raising the mountains on the seafloor, which raised sea levels higher, flowing onto the continents (Unknown, n.d.). Hence, the climate changed accordingly; for example, they may have experienced “strong seasonal contrasts of temperature within large continental areas as well as some polar ice. Monsoonal effects were dominant on the continents and rainfall in low and mid latitudes was probably strongly seasonal, with arid conditions prevailing at low latitudes” (Hallam, 1993). In the late Jurassic, scientists noted a considerable spread of aridity in southern Eurasia and attributed this to orographic effects (Hallam, 1993). Although there are no concrete conclusions regarding the climate during the Jurassic times, we do know that the forests flourished and the dinosaurs grew larger than ever before.
Research has shown the flora distributions of the Jurassic period indicate a wide array of ferns, ginkgoes, conifers, bennettitaleans and cycads, many of which still exist today (Palmer, 2002). In the Jurassic life, the conifers were the most variegated of the large trees, and among those were the ginkgos. “Ginkoes carpeted the mid-to high northern latitudes, and podocarps, a type of conifer, were particularly successful south of the Equator” (Unknown, n.d.). The ostensibly palm-like cyads were very diverse and abundant; so much so that the Jurassic period could also be referred to as “the Age of the Cycads”
