US EditionDinos hatched eggs less efficiently than modern birds, researchers show
Oviraptors used a mixed incubation method combining parental body heat and sunlight, resulting in lower efficiency and potential asynchronous hatching, researchers in Taiwan found.
- Published 17 March 2026 in Frontiers in Ecology and Evolution, researchers in Taiwan recreated a life-sized oviraptor nest to test incubation hypotheses and found oviraptors likely combined parental warmth and sunlight.
- Oviraptor clutch geometry showed wide concentric rings with an open centre, so Heyuannia huangi built semi-open nests that likely prevented thermoregulatory contact incubation.
- The team built a model oviraptor with artificial eggs and used Thermometers 1 and 2 in experiments showing outer-ring eggs differ by up to 6°C in cooler air and about 0.6°C in warmer air.
- The experiment suggests oviraptor incubation efficiency was much lower than modern birds, with longer incubation periods and mixed parental–environmental heat explaining nest evolution from buried to semi-open.
- By showing how sunlight and parental warmth combined, authors argue the nest pattern balanced sunlight input and parental heat, reshaping interpretations of brooding fossils and incubation debates.

New research reveals dinosaurs used sun to help hatch eggs
Scientists in Taiwan examined the brooding behavior and hatching patterns of bird-like but flightless oviraptors.
Scientists Built a Life-Size Dinosaur Nest and the Results Were Surprising
Scientists recreated a life-sized oviraptor and nest to investigate how these bird-like dinosaurs hatched their eggs. How exactly did oviraptors, bird-like but flightless dinosaurs, hatch their eggs? Scientists have long debated whether these dinosaurs relied mainly on heat from the environment, similar to crocodiles and turtles, or used body warmth from a brooding adult like [...]
Dinos hatched eggs less efficiently than modern birds, researchers show
What do we really know about how oviraptors—bird-like but flightless dinosaurs—hatched their eggs? Did they use environmental heat, like crocodiles, or body heat from an adult, like birds? In a new Frontiers in Ecology and Evolution study, researchers in Taiwan examined the brooding behavior and hatching patterns of oviraptors. They also modeled heat transfer simulations of oviraptor clutches and compared hatching efficiency to modern birds. To …
Science is sometimes unfair. Oviraptors did not kidnap eggs (as their name accuses) but looked after them. They gave shelter to their own and others with equal care. They did so through direct body contact, as most current birds do. And, now it is known, also with the help of the sun. This is what a paper published this Tuesday by Asian researchers in the specialized journal Frontiers in Ecology and Evolution proposes. Continue reading
