Field Dispatches.
Half dev log, half field journal. We're building PaleoDex in the open and digging into the real fossil record — the science, the data, and the prehistoric life that doesn't get enough screen time. Sourced, bilingual, and never invented.

How Coprolites Form — and How to Prove One's Real
The chemistry behind fossilized dung, and the checklist paleontologists use to rule out an ordinary rock.
Why a Dinosaur Ate Rotten Wood on Purpose
A hadrosaur's fossilized dung is packed with fungus-eaten wood — one of the strangest diets a coprolite has ever revealed.
Human Coprolites: Ancient Poop, Ancient DNA
8,000-year-old human waste from an Oregon cave helped rewrite when people reached the Americas — and yes, a famous Viking one exists too.
Reconstructed Upside Down and Backwards
Hallucigenia was named for its dream-like strangeness in 1977, then published standing on its own spines, with a blob of decay fluid labelled as the head. The real one turned up in 2015.
The Skull on the Wrong End
In 1868 Edward Cope built a sea reptile with its skull on the tip of its tail. Everyone says his rival Marsh caught the blunder — but it was Joseph Leidy, in public, in 1870.
The Taung Child: The Discovery the Experts Rejected
In 1925 a young anatomist called a child's skull a human ancestor. The experts ignored it for 20 years, until Robert Broom's fossils and a famous forgery proved him right.
Archaeopteryx: The Fossil That Arrived Right on Cue for Darwin
Two years after Origin of Species, a German quarry produced a feathered animal with teeth and a bony tail. The £700 skeleton, the critic who called it a bird, and the 2025 specimen that showed it could fly.
Mary Anning: The Fossil Hunter History Nearly Forgot
From age 12, she pulled ichthyosaurs, plesiosaurs and Britain's first pterosaur out of deadly English cliffs, and got almost none of the credit. The real, sourced story.
The Carnotaurus Courtship Dance: What's Real, What's Guesswork
Prehistoric Planet's viral dance scene, fact-checked: the genuinely strange real anatomy, the contested science over the tiny arms, and what the show invented outright.
Tanis: The Day the Dinosaurs Died?
A North Dakota fossil bed seems to freeze the hours after the asteroid hit — fish with impact glass in their gills. Extraordinary, and one of the most disputed sites in paleontology.
The Coelacanth: The Fish That Came Back From Extinction
In 1938 a fishing boat hauled up a fish thought extinct with the dinosaurs. The coelacanth's real story, and why "living fossil" is only half true.
Piltdown Man: The 40-Year Hoax That Fooled Science
Britain's most famous fossil was a human skull glued to an ape's jaw. How chemistry exposed it, and why the forger is still unknown.
Amber's DNA Myth, and What It Actually Preserves
A real 1990s science claim helped inspire Jurassic Park. It didn't hold up, but what amber actually preserves is stranger, and just as real.
Is Brontosaurus Real? The Dinosaur Science Erased
Erased by science in 1903, revived in 2015, and still contested today. The real, sourced story of the most famous dinosaur that almost wasn't.
The Two-Headed Reptile of the Cretaceous
A baby reptile fossilized 120 million years ago with two skulls and one tiny body, and the glitch that still makes two-headed snakes today.
The Bone Wars
Two scientists hated each other so much they spent 20 years sabotaging fossil digs — and accidentally named most of the dinosaurs you know.
The deadliest carnivore in the fossil record
Ranked by bite force, feeding traces and crushed bone — three predators, and the deadliest isn't the T-Rex.
The 7 wildest fossil discoveries of 2025
A zombie fungus in amber, a new human ancestor, and the oldest armored dinosaur ever — the year in fossils, counted down.
Paleoflora: the forests that fed the giants
Coal, continental drift, Darwin's mystery — the overlooked science of ancient plants.
Coprolites: the serious science of fossil poop
Diet, behavior, even rewriting when grass evolved — what fossilized dung reveals.
Jurassic Park vs the fossil record
What the movies got wrong, what they got right — and the one invention we can't stand.
Field Log 001: building a real-fossil app from Chile
Why PaleoDex refuses to invent a single creature — the origin story.
Every creature in PaleoDex really existed
What 'real data' actually means, and why we leave blanks instead of guessing.
The Ice Age giants beneath Santiago
Notiomastodon, Megatherium and Hippidion — the megafauna under your feet.
