Unveiling Teoplati: A Dinosaur’s Battle with Disease

Welcome to the Natural History Museum in Zurich, where the majestic skeleton known as "Teoplati" stands tall. At first glance, it appears to be just another ancient fossil, but a closer inspection reveals a terrifying secret: this dinosaur suffered from a debilitating bone infection.

A Stunning Discovery from 220 Million Years Ago

Teoplati, an eight-meter-long Plateosaurus that roamed Switzerland’s landscapes 220 million years ago, met its untimely demise in a mud pit—a fate that seems tragically fitting for this creature, which had already been grappling with severe health issues.

Caught in the Mud: How a Chronic Infection Led to Its Fate

In the Late Triassic epoch, the Frick Valley was a dry yet flood-prone region, creating a perfect trap for unsuspecting dinosaurs like Teoplati. While many dinosaurs met their end in similar ways, this particular Plateosaurus faced a worse plight due to an agonizing infection in its right arm.

High-Tech Analysis Reveals Age-Old Illness

Discovered in 2018, researchers from the University of Zurich, alongside experts from the Frick Dinosaur Museum, have recently studied Teoplati’s bones using advanced CT scanners. This technology, typically reserved for industrial use, unveiled a stunning diagnosis: Teoplati likely suffered from osteomyelitis, a grave infection affecting bone tissue.

Osteomyelitis: A Timeless Threat

"Osteomyelitis is still a concern today, affecting numerous living species, from mammals to reptiles," noted Jordan Bestwick, a paleontology expert. Although this condition has been documented in various dinosaur groups, the extensive infection in Teoplati’s shoulder and upper arm is exceptionally rare.

Teoplati’s Legacy: A Tale of Injury and Misfortune

The museum has meticulously displayed Teoplati’s skeleton in the very position it was found. The adjacent life-sized reconstruction illustrates not just how this dinosaur appeared in life, but highlights the deformities caused by its chronic condition.

A Narrative of Survival Through Art and Reconstruction

Museum curator Dennis Hansen explains, “We crafted an exhibit that narrates the poignant saga of this dinosaur.” Visitors will encounter a diorama showcasing cracked mud and life-like footprints—Teoplati's last moments before sinking into its muddy grave.

An Individual Story Written in Bones

Teoplati isn’t merely a prehistoric relic; it's a powerful reminder of survival and tragedy. This exhibit uniquely combines scientific inquiry with a heartfelt narrative, allowing visitors to engage with a true story of life and fate.
