In 2025, dinosaurs had been all over the place. In Would possibly, the BBC revived their landmark collection Strolling With Dinosaurs, whilst July noticed the discharge of Jurassic International Rebirth, the 7th movie within the extinction-proof Jurassic Park franchise.
Emerging public sale costs for dinosaur skeletons had been a wealthy supply of media headlines and educational worry. And a record-breaking collection of guests (6.3 million in 2024–2025) flocked to the Herbal Historical past Museum in London, the place dinosaurs are a key draw.
A golden technology in dinosaur science is riding this fascination with dinosaurs. Round 1,400 dinosaur species are referred to now from greater than 90 nations, with the velocity of discovery accelerating within the remaining twenty years. The yr 2025 has to this point observed the invention of 44 new dinosaur species – just about one per week.
Many new discoveries come from palaeontological hotspots, comparable to Argentina, China, Mongolia and the USA, however dinosaur fossils also are being discovered in lots of different puts, from a Serbian village to the rainswept coast of north-west Scotland. At the same time as a researcher, it’s laborious to stay monitor, however here’s a private view of one of the yr’s highlights.
Zavacephale rinpoche
Some fossils are so thrilling that after first proven at educational meetings, they draw audible gasps even from skilled palaeontologists. Zavacephale is this sort of. The beautiful skeleton of this one-metre-long plant-eating dinosaur was once came upon in 110-million-year-old rocks within the Gobi Wasteland of Mongolia and described by way of palaeontologist Tsogtbaatar Chinzorig and co-workers.
Zavacephale is the oldest identified member of the pachycephalosaurs, a gaggle of dinosaurs famed for his or her domed skulls, almost certainly used to butt heads like these days’s bighorn sheep. Pachycephalosaurs have lengthy been one of the enigmatic dinosaur teams, and the invention of Zavacephale is important to working out their early evolution.

Istiorachis macarthurae
Dinosaur fossils had been not unusual discoveries within the swiftly eroding Cretaceous Duration-aged cliffs of the Isle of Wight, off the south coast of England, for just about two centuries. But, even right here, there may be a lot to be informed. Jeremy Lockwood, a retired physician became dinosaur professional, has since 2021 named 3 new species of huge ornithopods, one of the not unusual teams of plant-eating dinosaurs. Those new species are carefully associated with Iguanodon, a four-legged ornithopod from Belgium with an excessively unique thumb spike.
Lockwood’s newest discovery, the six-metre-long Istiorachis, is any other herbivorous ornithopod with a placing sail-like construction operating alongside its again. This sail can have been a show construction used to draw pals and to discourage predators by way of making this 128-million-year-old animal glance larger.

Spicomellus afer
Spicomellus was once named in 2021 in keeping with an incomplete rib from 165-million-year-old rocks in Morocco. This is a rib in contrast to that during some other animal, alive or extinct, with a chain of lengthy spines fused to its floor. In 2025, I used to be a part of a crew led by way of researcher Susie Maidment that described a a lot more whole skeleton. It published one of the vital strangest dinosaurs ever came upon.
The brand new fossils display that Spicomellus is the oldest identified member of the ankylosaurs, closely armoured, low and squat plant-eaters described by way of Maidment as similar to “walking coffee tables”.
Spicomellus is characterized by way of its abnormal armour, bristling with lengthy spines in all places the frame, together with a bony collar across the neck with spines the duration of golfing golf equipment protruding of it. Dubbed the “punk rock dinosaur” by way of the BBC, Spicomellus is converting our working out of ankylosaur evolution, but in addition highlighting the significance of the Moroccan fossil listing.
Nanotyrannus lethaeus
For a few years, one of the vital fiercest debates in dinosaur palaeontology has been about Nanotyrannus, a 66-million-year-old predator from Montana in the USA. Nanotyrannus was once first named in 1988, and instructed to be a small tyrannosaurid, round 5m lengthy, that lived along the enormous Tyrannosaurus rex. However many different palaeontologists disagreed, suggesting that fossils of Nanotyrannus had been simply younger people of T rex.
In 2025, palaeontologists Lindsay Zanno and James Napoli revealed an outline of a brand new Nanotyrannus fossil specimen, preserved as a part of the Duelling Dinosaurs fossil along a herbivorous Triceratops. They confirmed that this Nanotyrannus was once just about an grownup, but in addition that it was once other from T rex in loads of tactics that can not be defined by way of expansion, together with an extended hand.
A next find out about at the unique Nanotyrannus demonstrated that this specimen was once additionally totally grown. In combination, those research finish a 35-year-long controversy and divulge Nanotyrannus as a slim, agile pursuit predator, constructed for pace.

Huayracursor jaguensis
Gigantic, four-legged, long-necked, plant-eating sauropod dinosaurs of the Jurassic and Cretaceous classes, comparable to Brachiosaurus, had been the most important animals to ever stroll the Earth, weighing as much as 70 tonnes (similar of 12 African elephants). The yr 2025 noticed many new sauropod discoveries, together with a Jurassic Freeway of trackways introduced by way of our crew from a quarry in Oxfordshire, UK.
Essential new data on sauropod origins got here from the Triassic Duration rocks of Argentina, lengthy a key supply of dinosaur discoveries. The 2m lengthy Huayracursor was once described from 228-million-year-old rocks within the Andes, making it one of the vital oldest identified sauropod ancestors. It has a for much longer neck than different species from the break of day of dinosaur evolution, revealing the earliest phases within the evolution of the intense neck elongation observed in later sauropods.

The yr 2025 was once any other outstanding yr for dinosaur discovery and 2026 may have so much to reside as much as. However I’m taking a look ahead to seeing what surprises the brand new yr brings.
