Dinosaur Footprints

The dinosaurs were a group of land animals that lived during the Mesozoic era for approximately 165 million years, and went extinct (along with many other animals and plants) at the end of this era, in a sudden event known as the Cretaceous-Tertiary Extinction. For most of the time that dinosaurs were around they were the dominant land animals, and they included the ancestors of birds (in modern systems of biological classification, known as “cladistics”, birds are technically a subgroup within dinosaurs).

We know a lot about dinosaurs because of the fossils that they left. The best-known fossils are of course the bones, teeth and horns (and sometimes soft body parts such as skin impressions) of the dinosaurs, which are of course displayed in many different museums around the world. Sometimes dinosaurs also left fossils, known as trace fossils (technically “ichnofossils”), which show their activities during life – these include fossilized dung (known as “coprolites”), nests, burrows, toothmarks, and footprints.

Fossilized dinosaur footprints have been found in many locations around the world. Typically they are formed when a dinosaur walked across wet sand (for example), and this was buried by mud or silt. Later these materials turned to rock, and millions of years later we found these impressions of dinosaur’s feet embedded within rocks.

Scientists can tell a lot from dinosaur footprints. Apart from the size and shape of the shape of dinosaur’s feet that is! They may be able to get an idea of the particular dinosaur’s weight, and if there are a series of footprints, how fast it was moving, whether it walked on two or four legs, whether it was travelling in a group, whether the group included both juveniles and adults, and much else besides.

Dromaeosauridae $59.89 Dromaeosauridae is a family of bird-like theropod dinosaurs. They were small to medium-sized, feathered carnivores that flourished in the Cretaceous Period. In informal usage they are often called raptors (after Velociraptor), a term popularized by the film Jurassic Park. The name Dromaeosauridae means ”running lizards”, from Greek dromeus meaning ”runner” and sauros meaning ”lizard”. Dromaeosaurid fossils have been found in North America, Europe, North Africa, Japan, China, Mongolia, Madagascar, Argentina, and Antarctica. They first appeared in the mid-Jurassic Period (Bathonian stage, 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 65.5 ma), existing for over 100 million years, up until the Cretaceous-Paleogene extinction event. The presence of dromaeosaurs as early as the Middle Jurassic has been confirmed by the discovery of isolated fossil teeth, though no dromaeosaurid body fossils have been found from this epoch.

Fossils Of The Gault Clay $31.95 The Albian (Lower Cretaceous) Gault Clay of south-east England and north-east France covers only a small area, but contains a wide variety of well-preserved vertebrate and invertebrate fossil remains.

Hell Creek: 65 Million Years in the Past, the Journey Begins $18.54 The Hell Creek fossil bed is a paleontologist’s dream…. until the fossils come to life. A long-extinct beetle is created in a particle physics lab. An unstable Graviton Vault hurls four-and-a-half people and a dog onto a beach inhabited by toothed gulls and fifty-foot crocodiles. There will be no rescue party: for paleontologist Julian Whitney must convince his companions that they are still in the same location – 65-million years in the past, at the end of the Age of Dinosaurs. How can they hope to return home, with the Vault perhaps destroyed, and a hypothetical reversion point a thousand miles away in the Cretaceous wilderness? 65-million years in the future, police chief Sharon Earles tries to solve the mystery of exactly half a body remaining where five people had been moments before. Physicists are brought in to repair the equipment and figure out what went wrong. But can they get the Vault running in time to retrieve the missing people…and do they want to? Most prehistoric fiction brings dinosaurs into our time, where they clash with Man’s synthetic world. Hell Creek does the opposite. From the great Inland Sea to the foothills of the infant Rocky Mountains, we are shown the entirety of an ecosystem. The authors’ scientific knowledge of Earth’s geologic and evolutionary history gives the story, and the titanic animals it is centered around, a realism that is refreshing – and immensely entertaining.

The Dawn Angiosperms $129 This book is about fossil plants of so-called pre-historic angiosperms. It reflects the newest progress in research on the origin of angiosperms, and will definitely trigger many new ideas in research. It emphasizes the early Cretaceous and Jurassic materials, rather than later ones, as they are the key periods for the origin of angiosperms.The author integrates multiple techniques, including SEM, TEM, light microscopy, peeling and cladistics, to study the morphology, anatomy and phylogeny of the fossils. Several Jurassic materials of angiosperms that have never been reported before are included, these used to be thought as pre-historic for flowering plants. Two more fossils angiosperms from the Yixian Formation, where Archaefructus was excavated, are reported. Newer and stricter criterion for identifying fossil angiosperms is proposed.

The Jurassic: The Mammal Explosion – History and Analysis of the Discovery Today Challenging the Conventional View of Our Ancestors $15.79 Conventional paleontology, solely based on the body fossil record, had claimed – if not imposed – that the entire contemporary Mammal Class, from mice to whales, including primates from whom we stem, had evolved from a small group of shrew-like early mammals known as Morganucodonts, following the demise of the dinosaurs 65 million years ago. This theory had surmised that predatory dinosaurs, known as Theropods, had fed upon early mammals from the beginning of the Jurassic to the end of the Cretaceous, hereby keeping their size and numbers small, rare, nocturnal, and insectivores. And that the only ones that managed to survive this intense predation up until the demise of the dinosaurs were these very small and fossorial Morganucodonts. This book describes the discovery made in the late 1990′s in southeastern Utah that challenges, if not confirms, that early mammals had not only diversified by the very beginning of the Jurassic from very small prey animals to fairly large carnivorous species, but were, numerically speaking, the dominant terrestrial species from the Jurassic onward to modern times. This book further heralds the use of inter-disciplinary determinations to solve complex issues as the one posed by the dinosaurs-mammals relationship.
