Atractosteus strausi – The armored hunter from the oil shale
An icon from the Hunsrück slate.
Arguably the most distinctive predatory fish from the UNESCO World Heritage Site, the Messel Pit. While the diversity of the Messel fauna is often highlighted by mammals, this fish embodies the archaic power of Eocene waters like no other. As a “living fossil,” it still offers us insights today into a world that dates back 47 million years.
An outstanding specimen of a bonefish from the oil shale deposits of the Messel Pit. The genus still exists today; a typical example is the alligator gar from the southern United States, whose morphology is very similar to that of this fossil. With a length of 28 cm, this specimen is among the largest found to date. Note the diamond-shaped, armor-like scales. They are coated with ganoin, which gives them a shiny appearance. Modern alligator gar are said to have been capable of deflecting small-caliber bullets fired by hunters.
Scientifically interesting: A survivor from prehistoric times
- Ganoid scale carapace: Unlike modern fish, Atractosteus is covered with a dense carapace of rhomboid, shiny scales. These gave it protection and make it one of the most aesthetically pleasing fossils at the site today.
- Specialized lurking hunter: Its elongated jaws, studded with needle-sharp teeth, are evidence of a highly specialized way of life. It is the direct ancestor of today’s bony pike and has hardly changed its design over millions of years.
- A masterpiece of fossil preparation: Due to the water-bearing oil shale, fossils from Messel must be embedded using the complex transfer method (epoxy resin). An Atractosteus that has survived this procedure perfectly is a testament to the highest level of preparation craftsmanship.
The fine details – what collectors look out for:
- The “shiny effect”: The most striking feature is the shiny surfaces of the scales (ganoin). On top specimens, this enamel-like sheen is as fresh as if the animal had been fossilized only yesterday.
- Complete dentition: A special quality feature is the preservation of the fine canine teeth in the pointed snout area. These are often the first parts to be lost during salvage.
- Dynamic posture: While stretched animals look classic, a slight curvature of the body gives the fossil an almost lively dynamic that captures the moment of embedding in the primeval mud.
A centerpiece for any Messel collection
Atractosteus strausi is the ultimate symbol of the subtropical lake landscape of the Eocene. It combines scientific relevance with an incomparable, almost sculptural aesthetic – an indispensable specimen for lovers of the local Tertiary fauna.
