The Late Cretaceous is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after creta, the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period.
Sauropoda, whose members are known as sauropods, is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads, and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include Brachiosaurus, Diplodocus, Apatosaurus, Camarasaurus and Brontosaurus.
Sauroposeidon is a genus of sauropod dinosaur known from several incomplete specimens including a bone bed and fossilized trackways that have been found in the U.S. states of Oklahoma, Wyoming, and Texas.
Walking with Dinosaurs is a 1999 six-part nature documentary television miniseries created by Tim Haines and produced by the BBC Studios Science Unit, the Discovery Channel and BBC Worldwide, in association with TV Asahi, ProSieben and France 3. Envisioned as the first "Natural History of Dinosaurs", Walking with Dinosaurs depicts dinosaurs and other Mesozoic animals as living animals in the style of a traditional nature documentary. The series first aired on the BBC in the United Kingdom in 1999 with narration by Kenneth Branagh. The series was subsequently aired in North America on the Discovery Channel in 2000, with Avery Brooks replacing Branagh.
Sea Monsters, marketed as Chased by Sea Monsters in the United States, is a 2003 three-part nature documentary television miniseries created by Impossible Pictures and produced by the BBC Studios Science Unit, the Discovery Channel and ProSieben. Following in the footsteps of The Giant Claw (2002) and Land of Giants (2003), special episodes of the nature documentary series Walking with Dinosaurs, Sea Monsters stars British wildlife presenter Nigel Marven as a "time-travelling zoologist" who travels to seven different periods of time in prehistory, diving in the "seven deadliest seas of all time" and encountering and interacting with the prehistoric creatures who inhabit them. The series is narrated by Karen Hayley.
Megaraptor is a genus of large theropod dinosaur that lived in the ages of the Late Cretaceous. Its fossils have been discovered in the Patagonian Portezuelo Formation of Argentina, South America. Initially thought to have been a giant dromaeosaur-like coelurosaur, it was classified as a neovenatorid allosauroid in previous phylogenies, but more recent phylogeny and discoveries of related megaraptoran genera has placed it as either a basal tyrannosauroid or a basal coelurosaur with some studies still considering it a neovenatorid.
The Lost World is a 2001 British made-for-television film adaptation of the 1912 novel of the same name by Arthur Conan Doyle, directed by Stuart Orme and adapted by Tony Mulholland and Adrian Hodges. It was filmed at various locations on the West Coast of New Zealand. The 145-minute film was divided into two 75-minute episodes when broadcast on BBC One on 25 and 26 December 2001, receiving 8.68 million and 6.98 million viewers respectively. Bob Hoskins played Professor Challenger and was supported by James Fox, Peter Falk, Matthew Rhys, Tom Ward and Elaine Cassidy.
Tyrannosaurus rex is unique among dinosaurs in its place in modern culture; paleontologist Robert Bakker has called it "the most popular dinosaur among people of all ages, all cultures, and all nationalities". Paleontologists Mark Norell and Lowell Dingus have likewise called it "the most famous dinosaur of all times." Paleoartist Gregory S. Paul has called it "the theropod. [...] This is the public's favorite dinosaur [...] Even the formations it is found in have fantastic names like Hell Creek and Lance." Other paleontologists agree with that and note that whenever a museum erects a new skeleton or bring in an animatronic model, visitor numbers go up. "Jurassic Park and King Kong would not have been the same without it." In the public mind, T. rex sets the standard of what a dinosaur should be. Science writer Riley Black similarly states, "In all of prehistory, there is no animal that commands our attention quite like Tyrannosaurus rex, the tyrant lizard king. Since the time this dinosaur was officially named in 1905, the enormous carnivore has stood as the ultimate dinosaur."
Puertasaurus is a genus of sauropod dinosaur that lived in South America during the Late Cretaceous Period. It is known from a single specimen recovered from sedimentary rocks of the Cerro Fortaleza Formation in southwestern Patagonia, Argentina, which probably is Campanian or Maastrichtian in age. The only species is Puertasaurus reuili. Described by the paleontologist Fernando Novas and colleagues in 2005, it was named in honor of Pablo Puerta and Santiago Reuil, who discovered and prepared the specimen. It consists of four well-preserved vertebrae, including one cervical, one dorsal, and two caudal vertebrae. Puertasaurus is a member of Titanosauria, the dominant group of sauropods during the Cretaceous.
When Dinosaurs Roamed America is a two-hour American television program that first aired on the Discovery Channel on July 15, 2001. The show features the reign of the non-avian dinosaurs in America over the course of more than 160 million years, through five different segments, each with their own variety of flora and fauna.
Nigel Alan Marven is a British wildlife TV presenter, naturalist, conservationist, author, and television producer. He is best known as presenter of the BBC miniseries Chased by Dinosaurs, its sequel, Sea Monsters, as well as the ITV miniseries Prehistoric Park. He is also known for his unorthodox, spontaneous, and daring style of presenting wildlife documentaries as well as for including factual knowledge in the proceedings.
Caenagnathidae is a family of derived caenagnathoid dinosaurs from the Cretaceous of North America and Asia. They are a member of the Oviraptorosauria, and relatives of the Oviraptoridae. Like other oviraptorosaurs, caenagnathids had specialized beaks, long necks, and short tails, and would have been covered in feathers. The relationships of caenagnathids were long a puzzle. The family was originally named by Raymond Martin Sternberg in 1940 as a family of flightless birds. The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods, and the discovery of more complete caenagnathid remains revealed that Chirostenotes pergracilis, originally named on the basis of a pair of hands, and Citipes elegans, originally thought to be an ornithomimid, named from a foot, were caenagnathids as well.
T-Rex: Back to the Cretaceous is a 1998 American educational adventure film shot for the IMAX 3D format. The film is directed by Brett Leonard. Executive producer/co-writer Andrew Gellis and producers Antoine Compin and Charis Horton also make up the production team. Liz Stauber and Peter Horton star, alongside Kari Coleman, Tuck Milligan, and Laurie Murdoch. When a museum accident transports teenager Ally Hayden on an adventure back in time, she explores the terrain and territory of life-sized dinosaurs, even during a nose-to-nose encounter with a female Tyrannosaurus. The film is among the few IMAX films that are considered "pure entertainment", though it still is considered rather educational by the mainstream audience.
Land of Giants and The Giant Claw, marketed together as Chased by Dinosaurs in the United States, are two special episodes of the nature documentary television series Walking with Dinosaurs.

Lognkosauria is a clade of giant long-necked sauropod dinosaurs within the clade Titanosauria. It includes some of the largest and heaviest dinosaurs known. They lived in South America and likely Asia during the Late Cretaceous period.
Paleontology in Arkansas refers to paleontological research occurring within or conducted by people from the U.S. state of Arkansas. The fossil record of Arkansas spans from the Ordovician to the Eocene. Nearly all of the state's fossils have come from ancient invertebrate life. During the early Paleozoic, much of Arkansas was covered by seawater. This sea would come to be home to creatures including Archimedes, brachiopods, and conodonts. This sea would begin its withdrawal during the Carboniferous, and by the Permian the entire state was dry land. Terrestrial conditions continued into the Triassic, but during the Jurassic, another sea encroached into the state's southern half. During the Cretaceous the state was still covered by seawater and home to marine invertebrates such as Belemnitella. On land the state was home to long necked sauropod dinosaurs, who left behind footprints and ostrich dinosaurs such as Arkansaurus.
