Deep-dives on dinosaur species, paleontology, and the science behind how we know what we know about prehistoric life. Built for curious kids, parents, and teachers.

Many dinosaurs had hollow bones — just like modern birds. Why this evolved, what it tells us about dinosaur biology, and why birds are technically dinosaurs.

Sixty-six million years ago, a 6-mile asteroid hit Earth and ended the dinosaur era. The evidence for the impact theory, what happened in the hours and years after, and what survived.

Florida has no native dinosaur fossils, but it has world-class prehistoric collections — megalodon, mastodons, ancient marine life. A guide to museums, fossil sites, and beaches.

Evolution explained for kids — what it actually is, how it works, why it matters, and how to teach it well. A clear guide drawn from biology and museum sources.

What a fossil actually is, how fossils form, the different types, and how you can find or make your own. A clear, citation-friendly guide drawn from primary museum sources.

Were dinosaurs warm-blooded like mammals and birds, or cold-blooded like modern reptiles? The current scientific consensus — it depends on the species — and the evidence.

What scientists actually know about Velociraptor — its real size, feathers, intelligence, hunting behavior — and what Jurassic Park got wrong about everyone's favorite raptor.

Everything you want to know about Tyrannosaurus Rex — its size, what it ate, when it lived, why its arms were so small, and what scientists have learned in the last decade.

Everything about Triceratops — its three horns, the bony frill, what it ate, when it lived, how it defended itself, and how scientists figured it all out from bones.

About 252 million years ago, the Permian-Triassic extinction killed 90% of all species. What caused it, how it happened, and how it cleared the way for the rise of dinosaurs.

The 165-million-year reign of the dinosaurs across three periods. Triassic, Jurassic, and Cretaceous — what was different about each, what species lived, and how the era ended.

Stegosaurus had bony plates running down its back and spikes on its tail. What scientists know about its body design, what it ate, and why those plates evolved.

Spinosaurus was bigger than T-Rex and likely the only dinosaur built for life in water. Size, body design, what we've learned recently, and why the science keeps changing.

Pterosaurs ruled the skies of the dinosaur era. What they were, how they evolved flight, and why they were not actually dinosaurs (though they lived alongside them).

Mosasaurs ruled the oceans alongside the dinosaurs — giant marine reptiles up to 50 feet long. What they were, what they ate, and how they're related to modern lizards.

Megalodon was the largest shark in history — 60 feet long, with teeth bigger than a human hand. What scientists know about its size, diet, when it lived, and where its fossils are found.

Mastodons and mammoths were both prehistoric elephant relatives, but they were different species with different habits and diets. The differences, where they lived, and how to tell them apart.

From fossil discovery to scientific name — how paleontologists name new dinosaur species. The rules, the history, and why dinosaur names sound so unusual.

From bones to body shape, color, and behavior — how paleontologists reconstruct what dinosaurs really looked like, and what's confirmed vs educated guess.

From satellite images to careful excavation, here is how working paleontologists actually find dinosaur fossils. The full process, the tools, and how kids can practice the same skills.

Why animal bodies are shaped the way they are. A guide to adaptation in dinosaurs and modern animals — body features, behavior, and how scientists figure out what each one is for.

Florida has no dinosaur fossils, but its prehistoric past is one of the richest in North America — megalodon, mastodons, giant sloths, and ancient marine ecosystems. A guide.

Diplodocus was one of the longest land animals ever — and it could crack its tail like a whip. Size, behavior, and what scientists know about this Jurassic giant.

Did dinosaurs lay eggs? Yes. How did they care for them? What fossils show. A complete guide to dinosaur reproduction, nests, and parental care.

Tooth shape tells you what an animal eats. How dinosaur teeth differed between meat-eaters and plant-eaters, what kids can learn from comparing teeth, and what modern animals show.

Brachiosaurus was a long-necked giant that reached treetops other dinosaurs could not. Size, weight, diet, when it lived, and how scientists figured out its surprising posture.

Ankylosaurus was covered in bony armor and swung a tail like a club. The dinosaur built for defense, what it ate, and how it actually used that tail.

Allosaurus was the dominant predator of the Late Jurassic — the lion of its day. Size, hunting behavior, what it ate, and how it compared to T-Rex 80 million years later.
