Tharsis dubiusDescription: This is a fine positive example of a swift-swimming schooling fish from the lithographic limestone deposits of Eichstatt, Germany, known as Tharsis dubius. These 150 million year old deposits are famous for their exceptionally well-preserved organisms, the most famous of which are the handful of specimens of the ancient bird Archaeopteryx. That exceptional preservation is displayed here as well, down to the wonderfully-preserved caudal fin. They congregated in shoals, a habit that safeguarded individual specimens from predators. The genus went extinct at the end of the Jurassic.
