New 'hell heron' Spinosaurus species found in remote Sahara 70 years after fossil clue

Paleontologists have announced the discovery of a new species of Spinosaurus — the meat-eating dinosaur that may have rivaled T. rex in size.

The new species, called Spinosaurus mirabilis, lived 95 to 100 million years ago. The fossil remains were found in the Sahara Desert, in a remote location called Jenguebi, in the country of Niger.

Recently detailed in the journal Science, the discovery was years in the making — with researchers finding jaw fragments in 2019 and two additional crests in 2022.
