Fossils of a new dromaeosaur date to the end of the Age of Dinosaurs
Fossils from a new dromaeosaur recovered from New Mexico suggest these fierce predators were diversifying up to the end of the Age of Dinosaurs.
www.sciencenews.orgHere’s the latest notable information on Dromaeosaurids as of 2026:
- Recent work still recognizes Dromaeosauridae as a diverse group of feathered, predatory theropods that were widespread across North America, Asia, and other continents during the Cretaceous. Multiple Maastrichtian dromaeosaurids from North America contributed to the view that this family remained diversifying up to the end of the dinosaur era.[3][4]
- One particularly well-cited Maastrichtian North American find is Dineobellator notohesperus from New Mexico, described in 2020, which provided a more complete skeleton for a late Cretaceous dromaeosaurid and offered insights into tail mobility, forelimb strength, and ecological niche partitioning near Tyrannosaurus rex-dominated ecosystems.[4][3]
- Beyond Dineobellator, other late Cretaceous dromaeosaurids from North America (e.g., Velociraptorinae members) have been discussed in phylogenetic and biogeographic contexts, supporting ideas of both end-Cretaceous diversity and possible regional vicariance events after dispersal from Asia.[3][4]
- In broader syntheses, dromaeosaurids are frequently cited as key models for understanding predatory adaptations (including sickle-shaped claws and agile bodies) and their persistence up to the K-Pg boundary, though the fossil record from the Maastrichtian remains incomplete and new finds can shift phylogenetic placements.[5][3]
If you’d like, I can assemble a concise timeline of major Maastrichtian dromaeosaurid finds and their implications, or pull a short annotated bibliography of the most-cited recent sources. I can also summarize what Dineobellator reveals about behavior and ecology with a couple of bullet points.
