10The Yo-Yo Injury
In 2005, Dazzling Dave visited schools in North Dakota. The professional yo-yo performer entertained kids for up to 12 hours at a time. A week later, the man, whose real name was David Schulte, noticed that his right index finger warmed more slowly than the rest. In cold weather, it was also the first to freeze.
When it started shifting colors—alternating between red, purple, and blue—he sought medical help. The doctor suspected a blood clot. A scan showed something else entirely.
There was no blood flow past the second knuckle of the finger. For some reason, the blood vessels had suddenly constricted and for too long. The unusual injury was probably caused by years of hitting that particular finger with a yo-yo.
Technically, it caused a condition known as Raynaud’s syndrome which can result in nerve damage and tissue loss. Luckily, the champion yo-yo artist suffered no lasting problems. A month of popping blood thinners solved the situation.
In 2017, researchers riffled through the Natural History Museum in London. They found a game-changing fossil. The bones belonged to a carnivore called Teleocrater rhadinus.
When it was discovered in the 1930s, experts failed to find its place in the evolutionary tree. As a result, it was shelved and forgotten. The modern study determined that the creature was 245 million years old. It lived 10 million years before the dinosaurs. Even better, it was one of their ancestors.
Teleocrater‘s main surprise was a body structure more reminiscent of a crocodile than a dinosaur. In particular, they had crankles. Short for crocodile ankles, they gave the animal a reptilian gait on all fours like a monitor lizard.
This was significant. An impossibly long time ago, reptiles called archosaurs split into two lineages: the bird branch (which led to the dinosaurs) while the other remained reptilian, with today’s alligators and crocodiles.
Teleocrater is the earliest-known member from the bird line, but its crankles were like a strange missing link connecting it back to the archosaurs and the reptile branch. This profoundly challenged what scholars thought they knew about early dinosaur evolution.
