• Dinosaur Metabolism - Warm or Cold-Blooded?

  This article explores how dinosaurs regulated their body temperature, with evidence suggesting many were closer to "warm-blooded" than "cold-blooded." It covers posture, growth, isotopes, and more to show a complex picture of dinosaur metabolism.

• Evolution and Natural Selection

  Evolution is the process by which species change over time through variation, inheritance, and natural selection. It began at least 3.5 billion years ago, leading to the diverse life forms we see today.

  

• Hard Work or Guesswork? The Science Behind Our Knowledge of Dinosaurs

  This article explores the scientific methods behind our understanding of dinosaurs, including climate reconstruction, continental drift, metabolism, color, and behavior. It highlights the evidence and techniques used by paleontologists to piece together the ancient world, showing that our knowledge is based on solid research rather than mere guesswork.

• How Do Fossils Form?

  This article explores how fossils form, the different types (like bones, footprints, and coprolites), how paleontologists find and date them, and how new dinosaur species are identified from fossil evidence.

  

• Major Groups of Dinosaurs

  This article explores the major groups of dinosaurs, dividing them into Saurischians (including long-necked sauropods and bipedal theropods like T. rex) and Ornithischians (including horned, armored, and duck-billed dinosaurs like Triceratops and Stegosaurus). It explains key traits, evolutionary relationships, and the diversity of body forms and lifestyles across dinosaur clades.

• Paleontology - Much More Than Just Dinosaurs

  This article explores the many branches of paleontology beyond dinosaurs, highlights fascinating fossil discoveries, and discusses why investing in curiosity-driven research is crucial for scientific progress.

  

• The End-Cretaceous Mass Extinction

  This article explains the end-Cretaceous mass extinction 66 million years ago, caused by a massive asteroid impact that wiped out all non-avian dinosaurs and about 75% of life on Earth. It explores the evidence for the impact, the Chicxulub crater, global effects, extinction toll, and what survived.

  

• The Mesozoic Era

  The Mesozoic Era, spanning from 252 to 66 million years ago, was the "Age of Dinosaurs," marked by the evolution, dominance, and eventual extinction of non-avian dinosaurs. It consisted of the Triassic, Jurassic, and Cretaceous periods and saw major changes in climate, geography, and life on Earth.
