Megalania ("Megalania prisca" or "Varanus priscus") is an extinct giant goanna or monitor lizard.
 They were part of a megafaunal assemblage that inhabited southern Australia during the Pleistocene.
 The youngest fossil remains date to around 50,000 years ago.
 The first aboriginal settlers of Australia might have encountered them.
The Quaternary period saw the extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity, and the extinction of key ecological strata across the globe.
 The most prominent event in the Late Pleistocene is differentiated from previous Quaternary pulse extinctions by the widespread absence of ecological succession to replace these extinct species, and the regime shift of previously established faunal relationships and habitats as a consequence.
 The earliest casualties were incurred at 130,000 BCE (the start of the Late Pleistocene), however the great majority of extinctions in Afro-Eurasia and the Americas occurred during the transition from the Pleistocene to the Holocene epoch (13,000 BCE to 8,000 BCE).
 However, this extinction wave did not stop at the end of the Pleistocene, but continued, especially on isolated islands, in human-caused extinctions, although there is debate as to whether these should be considered separate events or part of the same event.
 Among the main causes hypothesized by paleontologists are overkill by the widespread appearance of humans and natural climate change.
 A notable modern human presence first appeared during the Middle Pleistocene in Africa, and started to establish continuous, permanent populations in Eurasia and Australasia from 80,000 BCE, and the Americas from 22,000 BCE.
 A variant of the former possibility is the second-order predation hypothesis, which focuses more on the indirect damage caused by overcompetition with nonhuman predators.
 Recent studies have tended to favor the human-overkill theory.
The megafaunal wolf ("Canis cf. lupus") was a Late Pleistocene – early Holocene hypercarnivore similar in size to a large extant gray wolf.
 It had a shorter, broader palate with large carnassial teeth relative to its overall skull size.
 This adaptation allowed it to predate and scavenge on Pleistocene megafauna.
 Such an adaption is an example of phenotypic plasticity.
Equus sivalensis is an extinct equid, discovered in the Siwalik hills.
 Remains date to 2.6 million years ago, and it is assumed that it was extinct during the last Ice Age, between 75,000 and 10,000 years ago, as part of the late Pleistocene megafaunal extinction.
 Remains have been found in middle to late Pleistocene locations in the Siwaliks and in Tamil Nadu, and recently, as a "Great Indian horse" in Andhra, dated to ca. 75,000 BP.
The Kumi Lizard is a cryptid reptile, possibly a giant monitor lizard, which allegedly once lived in New Zealand.
 It is similar to the giant extinct Australian lizard Megalania except that it allegedly lives in trees.
A neck frill is the relatively extensive margin seen on the back of the heads of reptiles with either a bony support such as those present on the skulls of dinosaurs of the suborder Marginocephalia or a cartilaginous one as in the frill-necked lizard.
 In technical terms, the bone-supported frill is composed of an enlarged parietal bone flanked by elongated squamosals and sometimes ringed by epoccipitals, bony knobs that gave the margin a jagged appearance.
 In the early 1900s, the parietal bone was known among paleontologists as the dermosupraoccipital.
 In some genera, such as "Triceratops", "Pentaceratops", "Centrosaurus" and "Torosaurus", this extension is very large.
 Despite the neck frill predominantly being made of hard bone, some neck frills are made of skin, as is the case with the frill-necked lizard of today that resides in Australia.
 The use of the neck frill in dinosaurs is uncertain; it may have been used for thermoregulation or simply as a defense mechanism.
 Indeed, during battles for territory, competing "Triceratops" crashed heads together with their elongated horns and the neck frill may have been employed as a kind of shield, protecting the rest of the animal from harm.
 However, usage of the neck frill in modern reptiles is better documented.
 Two chief and disparate examples are the horned lizards (genus "Phrynosoma") with a bony frill, and the frill-necked lizard (genus "Chlamydosaurus") with a cartilaginous frill.
 The frill-necked lizard's frill is mainly made up of flaps of skin, which are usually coloured pink, supported by cartilaginous spines.
 Similar to the portrayal of the dinosaur "Dilophosaurus" in Steven Spielberg's "Jurassic Park", frill-necked lizard puff out these neck frills on either side of its head when threatened.
 The lizards often raise their frills when battling for territory or when coming into contact with another lizard, especially during mating season.
 There is, however, no evidence that suggests that "Dilophosaurus" neither had nor didn't have the same abilities, as many of its features in the "Jurassic Park" film were mostly fictional.
Paleontology in Tennessee refers to paleontological research occurring within or conducted by people from the U.S. state of Tennessee.
 During the early part of the Paleozoic era, Tennessee was covered by a warm, shallow sea.
 This sea was home to brachiopods, bryozoans, cephalopods, corals, and trilobites. Tennessee is one of the best sources of Early Devonian fossils in North America.
 During the mid-to-late Carboniferous, the state became a swampy environment, home to a rich variety of plants including ferns and scale trees.
 A gap in the local rock record spans from the Permian through the Jurassic.
 During the Cretaceous, the western part of the state was submerged by seawater.
 The local waters were home to more fossil gastropods than are known from anywhere else in the world.
 Mosasaurs and sea turtles also inhabited these waters.
 On land the state was home to dinosaurs. Western Tennessee was still under the sea during the early part of the Cenozoic.
 Terrestrial portions of the state were swampy.
 Climate cooled until the Ice Age, when the state was home to "Camelops", horses, mammoths, mastodons, and giant ground sloths.
 The local Yuchi people told myths of giant lizard monsters that may have been inspired by fossils either local or encountered elsewhere.
 In 1920, after local fossils became a subject of formal scientific study, a significant discovery of a variety of Pleistocene creatures was made near Nashville.
 The Cretaceous bivalve "Pterotrigonia thoracica" is the Tennessee state fossil.
The frilled-necked lizard ("Chlamydosaurus kingii"), also known as the frilled lizard, frilled dragon or frilled agama, is a species of lizard which is found mainly in northern Australia and southern New Guinea.
 This species is the only member of the genus Chlamydosaurus.
Microposaurus (meaning "small eyed lizard"; from Greek μικρός, "small" + ὀπός, "face" or "eye" + σαῦρος, "lizard") is an extinct genus of trematosaurid temnospondyl.
 Fossils are known from the Cynognathus Assemblage Zone of the Beaufort Group (part of the Karoo Supergroup) in South Africa and the Rouse Hill Siltstone of Australia that date back to the Anisian stage stage of the Middle Triassic.
 These aquatic creatures were the short snouted lineage from Trematosaurinae.
Lizard Island is a national park on an island of the same name on the Great Barrier Reef in Queensland (Australia), 1624 km northwest of Brisbane and part of the Lizard Island Group that also includes Palfrey Island.
 Lizard Island is within Cook Shire.
