Classification

"...like set theory. Instead of linnean categories such as "Dinosaura", (or "mammalia" "reptilia" or any other taxonomic grouping above species level), there is only a nested series of monophyletic clades, one within the other, like layers of an onion, all based on the idea of a MRCA (Most Recent Common Ancestor)..." -[M. Alan Kazlev]-

Discusses "Problems with the Cladistic position" and "Cladistics and the Fossil Record". Cladistics - also called Phylogentic Systematics or Phylogenetic Taxonomy - is a method of classifying organisms by common ancestry, based on the branching of the evolutionary family tree.

Articles & Background Information

"Few subjects in the Earth sciences are as fascinating to the public as dinosaurs. The study of dinosaurs stretches our imaginations, gives us new perspectives on time and space, and invites us to discover worlds very different from our modern Earth..From a scientific viewpoint, however, the study of dinosaurs is important both for understanding the causes of past major extinctions of land animals and for understanding the changes in biological diversity caused by..."

Articles from 1996-99. "For many years claims were made by strict creationists that human footprints or "giant man tracks" occur alongside dinosaur tracks in the limestone beds of the Paluxy River, near Glen Rose Texas. If true, such a finding would dramatically contradict the conventional geologic timetable, which holds that humans did not appear on earth until over 60 million years after the dinosaurs became extinct. However."

Museums and Exhibitions

The largest preserved T.Rex.

A new discovery from Mongolia Exhibition/ Museum. "more than 30 of the best preserved and scientifically important dinosaur and other ancient animal fossils ever discovered in Mongolia's famed Gobi Desert."

An exhibit about the eighty million year old dinosaur fossils from Mongolia. "Eighty million year old dinosaur fossils from Mongolia were seen for the first time in the UK in a major exhibition 'Dinosaurs of the Gobi Desert' at The Natural History Museum in 1997...The sensational discovery of these fossils sparked off some of the most exciting dinosaur research of the last few decades."

There are impressions of several dinosaurs at this site.

"So, you think the dinosaurs were wiped out in a meteorite impact 65 million years ago? Think again! This idea of mass-extinction is so widely-held, even amongst scientists, that it is often cited as a fact. Paul Chambers discovers clear evidence to the contrary as he reports on a paradigm in revision.."

Truth is Stranger than Fiction - Dispelling Dinosaur Myths. "Dinosaurs occupy a vaunted niche in the public mind; the very word conjures up images of gargantuan, now-defunct beasts that ruled the Earth long ago, holding a reign of terror for some 160 million years, and then mysteriously vanishing with only their titanic bones as evidence of their existence. "Dinosaur" reaches deep into our psyche and drags out nightmares from culturally-embedded monster myths. What is the truth about dinosaurs that underlies the popular awe and mystique that shrouds them? What does modern science have to say about the dinosaurs?."

The Volcano-Greenhouse Theory - The K-T Extinctions Debate. "Sixty-five million years ago, some phenomenon triggered mass extinctions on the lands and in the oceans so profound that they define the geological boundary between the older Mesozoic Era."

The Magnitude of the K/T Extinction

"There have been many mass extinctions throughout the history of the Earth. Probably the most famous is the extinction that finally saw the end of the dinosaurs reign on the Earth, 65 million years ago. It wasn't just the dinosaurs that died out in this extinction. Whatever caused the death of the dinosaurs also caused the death of around 70% of all of the species on the Earth.."

A detailed extinction theory

"The North American continent and many of its creatures were barbecued 65 million years ago in an immense, white-hot "corridor of incineration" resulting from an asteroid impact in Mexico, scientists say..."

There are several articles on this site. This is an excerpt from The rex files; "Cruel, massive, scaly lizards, as tall as the tallest tree, always ugly and very often natural-born killers...For the past century dinosaurs have dominated our imaginations.."

"Dinosaur tracks are remarkably abundant in many areas, and provide rich sources of scientific information on dinosaur behavior, locomotion, foot anatomy, ecology, chronology, and geographic distributions..."

"Weeks of hard, hot labor paid off for paleontologist Paul Sereno and his team in the Sahara in 1997. The 39-year-old science superstar found the most complete spinosaur skeleton ever found. The 100-million-year-old creature, Suchomimus tenerensis, was about 36 feet (11 meters) long..." -[Abstract; National Geographic]-

"Join us now for an online egg hunt and catch the excitement of fossil researchers as they 'hatch' fossilized dinosaur eggs to reveal the embryos inside. Tour our museum of dinosaur hatchlings and meet the modelers..."

Evidence that Dinosaurs and Humans co-existed...

"a map of the roof (top surface) of a coal seam in an abandoned mine located in late Cretaceous rocks of the Blackhawk Formation, near Price, southeastern Utah.."

"We know that dinosaurs moved; they were vertebrates, and we have their trackways (sequences of footprints) preserved in certain sediments as fossils. One popular question is how fast did they move."

"Scott R. Woodward of Brigham Young University in Provo, Utah, reported in 1995 that he had detected pieces of DNA from 80-million-year-old bones. He identified the fragments as part of the cytochrome b gene from dinosaur mitochondria..."

Australia's Largest Ever Dinosaur Skeleton

"..One of the two most massive dinosaurs ever known has been uncovered in a barren stretch of Egypt, scientists announced Thursday...The 70-ton plant-eater was discovered in what is now the Sahara Desert. But eons ago the area was filled with mangrove swamps, said University of Pennsylvania researchers, who reported their findings.."

Very 'technical'.

Project on Development of Phu Wiang Dinosaurs, Amphoe Phu Wiang, Changwat Khon Khaen. "Fossil dinosaurs have been discovered at Phu Wiang National Park, Amphoe Phu Wiang, Changwat Khon Khaen since 1976. The first dinosaur bones ever found in Thailand came from this area. Over the years, nine sites of the dinosaur bones were discovered and excavated from the Sao Khua Formation of 130 Ma. Three new species of the dinosaurs are discovered and described..."

"If fossilization was simply replacement of bone with stone, fossil and living bones wouldn't be as chemically similar as they are, and the intricate details found in fossilized dinosaur bones would not have survived."
