3D model of a Scorpion Fish (NHMW-GEO-1988/0001/0049)

<p>3D scan of a fossilized 14 million year old scorpion fish (<em>Scorpaena prior</em>). This fossil was found in a quarry in St. Margarethen, Austria – a world-class lagerstätte. The holotype, the first specimen to describe a new species, of&nbsp;<em>Scorpaena prior</em>&nbsp;is also housed at the NHM Vienna.</p><p>The St. Margarethen Lagerstätte in Austria is known worldwide for its
excellently preserved fish. For a long time, paleontologists could not
figure out what phenomenon preserved the fossils so well. Recent
research has revealed that the tropical bay was probably rich in algae
blooms, and their proliferation created an anoxic milieu in which the
fish could no longer survive. The carcasses sank to the low-oxygen
bottom of the lagoon and were quickly covered with fine mud where they
were preserved for millions of years.&nbsp;<em>Scorpaena prior</em> with its impressive spines had few enemies 14
million years ago (Miocene). Still, it couldn’t survive the threat posed
by the algae. Today, scorpion fish are one of the most dangerous
species of fish: its venom causes long lasting and violent pain. It can
even be fatal for humans.&nbsp;The Tertiary limestone or “<em>Leithakalk</em>” this scorpion fish is
surrounded by is still quarried in St. Margarethen. It was a popular
stone for building among the Romans. In Vienna, the material was used
for almost all the grand architecture, including St. Stephen’s Cathedral
and most of the buildings along the Ringstraße.&nbsp;</p>
