He was small but feared: Enchodus petrosus, the so-called "saber-toothed herring" of the Cretaceous period, was one of the most agile predators of the primeval seas. Despite its modest body size, usually 30–50 cm, it was equipped with a feature that makes it unmistakable – and continues to fascinate paleontologists to this day.
Who was Enchodus?
Enchodus lived about 65–100 million years ago in the shallow epicontinental seas of the Cretaceous period, which then covered large parts of North Africa, Europe, and North America. Despite its nickname, it was not a true herring but belongs to the extinct family of Enchodontidae – a group of primitive ray-finned fish distantly related to modern salmon and pike.
Its most striking feature: long, dagger-like fangs in the upper and lower jaws that extended far beyond the mouth line. These teeth were not used for chewing but for gripping and holding fast prey – small fish and cephalopods.
A Fossil that Tells a Story
Enchodus fossils are among the most common fish fossils of the Cretaceous period and are found worldwide – particularly rich are the phosphate formations of Morocco, from where our specimens also originate. Typically preserved fossils include:
- Vertebrae – compact, well-preserved, and ideal for collections
- Teeth – the characteristic fangs are the genus's distinguishing feature
- Jaw fragments – rarer, but particularly impressive
The Enchodus vertebrae, despite their small size of 2–3 cm, are astonishingly preserved in detail. Their characteristic hourglass shape and fine surface structures make them a fascinating collector's item.
Enchodus and its Contemporaries
In the primeval seas of the Cretaceous period, Enchodus was part of a complex ecosystem. It hunted smaller fish – and was itself hunted. Its predators included:
- Mosasaurids – enormous marine reptiles up to 17 meters long
- Otodus obliquus – an early ancestor of the Megalodon, which also lived in the same waters
- Large ray-finned fish and early sharks
Enchodus fossils are therefore frequently found together with Otodus vertebrae – a silent witness to this primeval predator-prey relationship.
Why Collect Enchodus Fossils?
- Authenticity: Each vertebra is a genuine, unworked original from the Cretaceous period
- Accessibility: Compared to spectacular large fossils, Enchodus vertebrae are affordable – without losing scientific value
- Storytelling: They represent an entire ecosystem and an era that changed the Earth forever
- Combinability: Together with an Otodus vertebra, an impressive duo of hunter and hunted is created
Enchodus in Our Collection
At Nautilus Natural History, we offer original Enchodus petrosus vertebrae from the Moroccan phosphate formation – individually or in a combi-pack with an Otodus obliquus vertebra. All fossils come with a certificate of authenticity and in an elegant black display.
Discover the fascination of the Cretaceous period – and hold a 65-million-year-old piece of Earth's history in your hands.
