Patagonian Dinosaur Kank australis Hint at Ancient Fishing Dinosaurs

Argentine paleontologists describe Kank australis, a new unenlagiid theropod from the Late Cretaceous Chorrillo Formation near El Calafate, about 70 million years old and roughly 2.5–3 m long. Its neck musculature and sharp ridged teeth, plus a pronounced second-toe claw, suggest an active fish-eating lifestyle in riverine wetlands alongside fish fossils and other fauna. The find bridges unenlagiids across southern Patagonia, Antarctica, and northern Patagonia. Initial remains were found in 2018, with a key cervical vertebra identified in 2024 confirming a new species; the study was published online May 28, 2026 in the Journal of Vertebrate Paleontology.

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.
