New dinosaur species discovered deep in the Sahara Desert

Spinosaurus Morabis: Discovery in the Sahara Desert

Key Concepts:

• Spinosaurus Morabis: A newly discovered species of spinosaurid dinosaur, characterized by a unique crest and adaptations for piscivory (fish-eating).
• Spinosaurids: A group of large, carnivorous dinosaurs adapted to aquatic environments, prevalent in the Cretaceous period around the Tethys Sea.
• Piscivory: A diet consisting primarily of fish, evidenced by specialized dental and jaw structures.
• Cretaceous Period: A geological period lasting from approximately 145 to 66 million years ago, during which dinosaurs thrived.
• Tethys Sea: An ancient sea that separated Africa and Eurasia, a key habitat for spinosaurids.
• Keratin: A fibrous structural protein forming the covering of the Spinosaurus crest.

I. The Discovery and Expedition

A new species of dinosaur, Spinosaurus Morabis (Latin for “astonishing”), has been unearthed in the Sahara Desert, dating back over 95 million years. The discovery was the result of a large-scale expedition involving 20 young people who dedicated three months to excavating in a remote region of the Sahara. The team initially located a tooth and jaw fragments, leading to the subsequent discovery of the dinosaur’s distinctive crest – the initial indicator of a new species. Dr. Paul Sero describes the expedition as “extraordinary” and a “big chance” taken to explore a previously understudied region.

II. Characteristics of Spinosaurus Morabis

Spinosaurus Morabis is estimated to have been approximately 40 feet long, comparable in size to Tyrannosaurus Rex. However, unlike T-Rex, this dinosaur possessed unique adaptations for a primarily piscivorous diet. Key characteristics include:

• Teeth: Straight, curved, and lacking serrations – a significant departure from the teeth of other large theropods like T-Rex. The lower teeth interlock with the upper teeth to effectively snare slippery fish.
• Crest: A prominent, 2-foot-tall crest extending from the skull, covered in keratin. This crest is unlike any previously observed on predatory dinosaurs and is a defining feature of the new species. Reconstruction suggests the crest was covered in a living animal-like keratin covering.
• Jaws: Adapted for catching fish, allowing the dinosaur to effectively hunt in rivers and coastal regions.
• Hands & Claws: Possessed large hands with substantial claws, suggesting a capacity for grasping prey.

Dr. Sero refers to Spinosaurus Morabis as a “hell heron,” highlighting its predatory behavior of waiting in the water to ambush prey and its display-oriented nature.

III. Distinguishing Spinosaurus Morabis from Other Spinosaurids

While sharing common spinosaurid traits like the distinctive tooth shape, Spinosaurus Morabis is differentiated by its unique crest and low snout. This crest, with its keratin covering, is a key characteristic defining the species. The discovery challenges previous hypotheses suggesting spinosaurids were diving marine creatures, confirming they inhabited the margins of oceans and rivers. Dr. Sero emphasizes that this dinosaur would have been a formidable predator on land and near the shore.

IV. Paleontological Context and Future Discoveries

The discovery of Spinosaurus Morabis occurs during a period of increased dinosaur discoveries globally. Dr. Sero predicts a “heyday of dinosaur research” with many more species yet to be named. The expedition yielded 50 tons of fossils, including previously unknown raptors, crocodiles, and other creatures. The Sahara Desert is described as a “lost world,” representing the last continent where significant discoveries of immense creatures are still possible.

A 12-foot “superfish” was also discovered near the Spinosaurus Morabis remains, providing further insight into the dinosaur’s diet. Dr. Sero referenced a French monograph containing initial clues about a tooth found in the central Sahara, which ultimately led to the expedition.

V. Notable Quotes

• “This is what they share. They share this kind of tooth that is straight, curved, no serrations. Looks very different than a T-Rex tooth.” – Dr. Paul Sero, describing the characteristic spinosaurid dentition.
• “It is the last continent you’re going to be able to describe immense creatures by the dozen to give us some idea of what was inhabiting that world.” – Dr. Paul Sero, emphasizing the significance of the Sahara Desert as a source of new paleontological discoveries.
• “We’re in a age of discovery. We’re naming more dinosaurs now than we’ve ever named before.” – Dr. Paul Sero, highlighting the current pace of paleontological research.

VI. Synthesis and Conclusion

The discovery of Spinosaurus Morabis represents a significant advancement in our understanding of spinosaurid dinosaurs and the Cretaceous ecosystem of North Africa. The unique characteristics of this species, particularly its crest and adaptations for piscivory, provide valuable insights into the evolutionary history and ecological role of these large predators. The expedition’s success underscores the potential for further discoveries in remote regions like the Sahara Desert, promising a continued expansion of our knowledge of prehistoric life. The find confirms that we are currently living in a golden age of dinosaur discovery, with many more species awaiting unearthing and description.
