A new 47-egg clutch (MPM 447) from Brazil’s Late Cretaceous Bauru Group is the largest Mesozoic crocodyliform nest discovered, offering rare insights into their reproductive strategies, nesting behavior, and potential communal nesting; the eggs’ morphology suggests humid, semi-aquatic conditions, with ongoing research to identify the species and assess parental care at the site.
Scientists analyzed dinosaur tooth enamel to reconstruct Mesozoic atmospheric CO2 levels and photosynthesis, revealing that Earth's atmosphere contained significantly more CO2 and had higher plant productivity during that era, providing new insights into ancient climate dynamics.
A 100-million-year-old fossilized frog with eggs in its belly has been discovered in China, offering a rare glimpse into the species' life history. The frog likely belonged to the species Gansubatrachus qilianensis and had egg masses in its body, indicating sexual maturation before adulthood. The researchers believe the frog may have met its end during mating, possibly drowned by an amorous male, making it the first Mesozoic case of death linked to mating behavior.
