Inland Sahara Unveils Scimitar-Crest Spinosaurus Mirabilis

Scientists led by Paul Sereno describe Spinosaurus mirabilis, a new inland Sahara spinosaurid from Niger dating to about 95 million years ago. It has a distinctive scimitar-shaped crest and likely hunted fish in shallow water far from the sea, challenging the idea that spinosaurids were coastal. The crest may have been for display; the team used CT scans and 3D models to reconstruct the skull. The discovery suggests an inland habitat and a new evolutionary phase for the group, with fossils set to be displayed in Niamey and the find published in Science.

New Spinosaurus Species Reveals Shallow-Water Hunter in the Sahara

Paleontologists in Niger describe Spinosaurus mirabilis, a new species with a nearly half-meter tall, keratin-covered scimitar-shaped crest found in an inland river system, suggesting the predator waded in shallow waters rather than swam; the discovery challenges the idea of Spinosaurus as primarily aquatic and hints the crest served in social signaling.

Sword-horned Spinosaurus reveals inland river hunter, upending coastal predator idea

Paleontologists in Niger announce a new Spinosaurus species, Spinosaurus mirabilis, featuring a 20-inch sword-like horn and a unique jaw arrangement, discovered inland far from the coast. The fossil suggests this fish-eating predator lived in forested river systems and grew to roughly the size of a Tyrannosaurus rex, with a sail-like back, challenging the view that Spinosaurus hunted exclusively in marine environments.

New Spinosaurus crest sharpens river-dwelling dinosaur debate

A newly described Spinosaurus mirabilis from Niger (~95 million years ago) features a dramatic scimitar-shaped head crest and interlocking teeth, fueling the longstanding debate over whether Spinosaurus was aquatic, wading, or fish-hunting. The discovery—published in Science—suggests riverine adaptations and possible display signals, but researchers say more complete fossils are needed to settle exactly how this giant predator lived and hunted.

Sahara unearths Spinosaurus mirabilis with colossal head crest

A team led by Paul Sereno has identified a new Spinosaurus species, Spinosaurus mirabilis, from Niger’s central Sahara. The discovery includes jaw fragments, teeth, and three scimitar-shaped head crests up to about 50 cm tall, likely keratin-sheathed and brightly colored for display—the tallest cranial crest yet known in non‑avian dinosaurs. The inland site, dated to about 95 million years ago, suggests an wading, fish‑eating predator that lived far from the coast, challenging the idea that spinosaurids were coastal or aquatic. The findings, published in Science, are accompanied by 3D skull reconstructions and will be exhibited at the Chicago Children’s Museum.

Colossal Spinosaurus mirabilis Unearthed in the Sahara, Redrawing Fish-Eating Dinosaur Tales

Paleontologists led by Paul Sereno have named Spinosaurus mirabilis, a colossal new spinosaur discovered in Niger’s Sahara dating to more than 95 million years ago. It features a distinctive scimitar-shaped head crest and interlocking teeth suited for catching fish, and was found far from coastlines, suggesting a forested, riverine habitat. The skull was reconstructed in 3D and described in Science, reinforcing fish-eating traits while leaving open questions about how aquatic these dinosaurs truly were.

New Spinosaurus mirabilis unearthed in Niger, inland giant of the Cretaceous

Paleontologists in Niger have identified a new Spinosaurus species, Spinosaurus mirabilis, about 12 meters long and 5–7 tons, with a 50 cm head crest and interlocking, fish-trapping teeth. Found inland in the Sahara, the fossils indicate a shallow-water predator that hunted fish rather than a fully aquatic hunter, challenging prior aquatic-only hypotheses for Spinosaurus; this makes mirabilis the second known Spinosaurus species after S. aegyptiacus.

Inland Sahara Unearths a New Spinosaurus with an Unprecedented Skull Crest

Paleontologists led by Paul Sereno have named Spinosaurus mirabilis from inland Niger in the Sahara, a coastal-dwelling genus found far from the ocean. The specimen features a unique skull crest and crocodile-like teeth, hinting at a possible semi-aquatic lifestyle. The discovery, published in Science, challenges previous assumptions about where Spinosaurus lived and how its skull crest looked.

Top 5 Largest Animals to Have Roamed Earth, Including One Still Alive

The article highlights five of the largest animals to have ever roamed Earth, including the blue whale, Argentinosaurus, Patagotitan, Megalodon, and Spinosaurus, with the blue whale still existing today as the largest animal, while the others are extinct relics of the past.

"Revealing the Truth: Spinosaurus - Land or Water Predator?"

New research led by UChicago paleontologists challenges previous theories about the hunting habits of the sail-backed dinosaur Spinosaurus aegyptiacus, suggesting that it was a shoreline predator rather than an underwater hunter. The study reevaluates bone density calculations and statistical techniques used in previous research, concluding that Spinosaurus likely waded into waterways to ambush prey rather than diving deep. The findings shed light on the complexities of assessing the aquatic abilities of extinct species and highlight the importance of considering measurement errors and individual variations when analyzing bone density.

"Reevaluating Spinosaurus: Flaws in Aquatic Pursuit Hunting Theory Uncovered"

A recent study has raised doubts about previous research supporting the idea that Spinosaurus was a fully aquatic pursuit predator. The new study, led by University of Chicago’s Professor Paul Sereno and colleagues, critically assesses the methods of the prior research and identifies significant flaws, particularly in the statistical technique used. The findings emphasize the importance of using consistent and objective criteria when classifying behavior and taking measurement errors and individual variations into account when assessing bone density. The study challenges the notion that Spinosaurus was a deep diver and suggests that the dinosaur may have waded into waterways to ambush fish while keeping its toes anchored in the mud.

"Unraveling the Spinosaurus Mystery: New Insights into Its Hunting Behavior"

A new study on the Spinosaurus aegyptiacus, also known as the "heron from hell," suggests that the giant dinosaur likely hunted in shallow waters rather than diving deep for its prey. Researchers from the University of Chicago examined the bone density of the dinosaur and concluded that it wouldn't have been well-suited for diving. Instead, they believe the Spinosaurus ambushed fish in waterways while keeping its toes anchored in the mud, shedding light on the long-standing debate about its hunting behavior.

"Reevaluating Spinosaurus: Debunking the Deep-Sea Hunter Theory"

A new study challenges the idea that the Spinosaurus, a large carnivorous dinosaur, swam after its prey, instead suggesting that it waded and plucked its prey from the water. The debate among researchers centers on whether the dinosaur hunted from the shore, waded in the shallows, or swam in pursuit of its prey, with conflicting views on its swimming abilities. The latest research argues against the idea that Spinosaurus was a swimmer, citing bone density analysis and the dinosaur's body shape as evidence against its swimming capabilities.

"Reevaluating Spinosaurus: Uncovering the Truth About Its Aquatic Abilities"

A new analysis led by paleontologists from the University of Chicago reexamines the density of Spinosaurus bones to determine its aquatic behavior, challenging earlier suggestions that it pursued prey underwater. The study found major issues with the statistical technique used in a 2022 Nature study, highlighting the importance of consistent and objective criteria when assessing bone density and classifying behavior. The findings suggest that Spinosaurus was a wader, able to ambush fish in shallow waters, rather than a deep-diving predator.

Spain's new dinosaur sheds light on ancient meat-eaters.

Scientists in Spain have identified a new species of spinosaurus, named protathlitis cinctorrensis, that lived during the late Cretaceous period and walked on two legs. The researchers used phylogenetic analysis to better understand how species have evolved and concluded that it is a basal baryonychine, a subfamily of spinosaurids. The discovery of this new species in the same place as another type of spinosaurus means that the Iberian Peninsula was much more diverse than previously thought. The team believes that spinosaurids originated in western Europe during the Late Jurassic or Early Cretaceous period and then migrated to Africa and Asia.
