Earth has experienced five major mass extinctions that dramatically reshaped life on our planet. In this Cliff Notes–style breakdown, we quickly explore the causes and impacts of each extinction event and how they changed the course of evolution.We’ll cover:• Ordovician–Silurian extinction event – A massive ice age that wiped out around 85% of marine species.• Late Devonian extinction – A prolonged crisis that devastated reef ecosystems and ocean life.• Permian–Triassic extinction event – The largest extinction in Earth’s history, sometimes called “The Great Dying,” eliminating up to 90–96% of species.• Triassic–Jurassic extinction event – A volcanic catastrophe that cleared the way for dinosaurs to dominate the planet.• Cretaceous–Paleogene extinction event – The asteroid impact that ended the age of dinosaurs (except birds).This quick guide covers what caused each extinction, what died, and how life recovered—all in a fast, easy-to-understand overview.If you enjoy paleontology, prehistoric life, and Earth history, this video gives you the essential facts behind the Big Five extinctions that shaped the world we live in today.If you love prehistoric life, deep-time ecosystems, and behind-the-scenes paleo stories, you’re going to enjoy this conversation!

🦖 DinosaurSkeletons.co.uk — For museum-quality fossil replicas and decor:
Scientists have officially described a brand new species of Spinosaurus — Spinosaurus mirabilis — from the Sahara Desert in Niger. This massive predatory dinosaur lived about 95 million years ago during the Late Cretaceous and may have hunted fish in shallow rivers like a giant prehistoric heron.What makes Spinosaurus mirabilis so unique is its huge scimitar-shaped head crest, which could have been brightly colored and used for display. Fossils discovered in 2019 and 2022 revealed multiple crests and skull fragments that confirmed this was a completely new species within the famous spinosaurid family.This discovery is particularly exciting because it’s the first clear new species of Spinosaurus described in more than a century, and it may change how scientists think these dinosaurs lived and hunted. Instead of being fully aquatic predators, this species may have been a semi-aquatic wader stalking fish in inland river systems deep in the Sahara.In this video we break down the discovery, the fossils, and what Spinosaurus mirabilis tells us about the evolution of spinosaurs.📄 Original scientific paper:https://www.science.org/doi/10.1126/science.adx5486If you love prehistoric life, deep-time ecosystems, and behind-the-scenes paleo stories, you’re going to enjoy this conversation!👍 Like the video if you learned something new💬 Drop a comment with your favorite Triassic animal🔔 Subscribe for more interviews with paleontology creators and scientists🎟️ PREHISTORIC LIVE 2026 — GET YOUR TICKETS NOW!Happening May 1st and 2nd, this event is going to be unforgettable.

Most organisms that have ever lived on Earth completely disappeared.
So how do fossils form at all?
In this episode, we’re diving deep into the science of fossilization — from rapid burial and permineralization to chemical replacement, molds, casts, and even steinkerns. We’ll break down how minerals turn bone into stone, how trace fossils preserve behavior, and why the fossil record is incredibly incomplete.
But that’s not all…
We’re also exploring rare cases of dinosaur mummification — including preserved skin impressions, armor, and even evidence of coloration in specimens like Dakota and Borealopelta.
In this video, you’ll learn:
🦴 The step-by-step fossilization process
🪨 The difference between permineralization and replacement
🐚 What molds, casts, and steinkerns actually are
🌿 How carbonization preserves plants and soft tissue
🦖 How dinosaur “mummies” form
🌍 Why fossilization is one of the rarest processes in nature
Fossils aren’t just bones — they’re geological miracles.
If you love paleontology, dinosaurs, and deep time science, you’re in the right place.
Stay prehistoric. 🦖🔥

In this episode, I break down the fascinating hypothesis from Dr. Brian Curtice and Taylor Oswald suggesting that Ceratosaurus — a key theropod from the Morrison Formation — may have had sabre-like teeth similar to saber-toothed predators.
🦖🪓We explore:
🦷 How Ceratosaurus dentition compares to other theropods
🧠 Connections between its elongated teeth and the “sabertooth” morphology seen in machairodont cats
🔬 What this could mean for Ceratosaurus’s predatory ecology and niche
📊 Real scientific analysis on morphology and feeding behaviorThis idea challenges what we think about Ceratosaurus’s hunting style and its role in a complex Jurassic predator ecosystem.
If you love paleontology, dinosaur behavior, and jaw-dropping hypotheses, this episode is for you!
💬 Comment your thoughts — do you think Ceratosaurus could’ve been a Jurassic “sabertooth”?

For decades, paleontologists have argued over one question: Was Nanotyrannus a real dinosaur—or just a young Tyrannosaurus rex? In this episode, we settle the debate once and for all.
Join us as we present the definitive evidence confirming that Nanotyrannus lethaeus was a distinct tyrannosaur species. From its unique skull proportions and slender build to its specialized teeth and braincase structure, Nanotyrannus stands apart from T. rex in ways that can no longer be ignored.
We’ll examine:
🦴 The anatomy that separates Nanotyrannus from T. rex juveniles
🧬 Bone histology proving mature growth stages
📜 The fossil record — from the Cleveland Skull to “Jane”
🔬 The newest research redefining late Cretaceous tyrannosaurs
Forget the “juvenile rex” theory — the evidence is in, and Nanotyrannus lethaeus earns its rightful place in dinosaur history as the swift, intelligent predator of the Hell Creek ecosystem.
🔥 If you love dino-Westerns, supernatural horror, and hard-hitting revenge tales, this is the book you’ve been waiting for.
