New dinosaur species named after fossil analysis
Palaeontologists have identified a new species of dinosaur - 125 years after its fossil was found.
www.bbc.co.ukHere’s a concise update on the latest dinosaur discoveries as of 2025–2026 headlines.
What’s new
- Argentina Megraptorans: A new megaraptorid named Joaquinraptor casali was reported from Patagonia, with a notably complete skeleton and clues about its diet from a crocodile-bone bite. This find adds to the diversity of South American megaraptorans and helps fill gaps in their evolutionary history.[1][2]
- US and Chilean finds: Reports emerged of another dome-headed dinosaur species in Montana, and earlier Chilean discoveries of new dinosaurs (e.g., Gonkoken) highlighted ongoing reveals of regional diversity in South America and North America. These studies illustrate how fossil sites continue to yield fresh species while refining our understanding of Late Cretaceous ecosystems.[3][4]
Representative examples (context and significance)
- Joaquinraptor casali (Argentina): The specimen’s completeness supports more robust reconstructions of megaraaptorans’ anatomy and potentially their feeding strategies, offering a clearer window into carnivorous lineages just before the end-Cretaceous extinction.[2]
- Montana dome-headed dinosaur: Adds to the record of dome-headed herbivores in North America, contributing to the discussion of niche partitioning and diversity in Late Cretaceous plains.[3]
- Chilean Gonkoken and related finds: Demonstrate that multiple new dinosaur lineages remained to be described even in relatively well-studied regions, underscoring the global pace of paleontological discoveries.[4]
If you’d like, I can pull up more detailed summaries or create a quick chart comparing key traits (age, region, inferred diet, and estimated size) for the latest named species. I can also track ongoing discoveries from specific regions (e.g., Patagonia, Montana) or a particular time window if you have a preference.
