Final answer:
A massive volcanic eruption did occur near the end of the age of dinosaurs, coinciding with the asteroid impact that led to their extinction.
Step-by-step explanation:
The statement that a massive volcanic eruption occurred near the end of the age of dinosaurs is true. Around 66 million years ago, extensive volcanism began forming in what is now India, coinciding with the Yucatan asteroid impact at the end of the Cretaceous period. The resulting lava flows covered much of the region, and the release of volcanic gases, particularly sulphur dioxide, contributed to significant climate change. This catastrophic event, along with the asteroid impact, may have induced the mass extinction that led to the end of the dinosaurs.
Fossil evidence also indicates that after this period, called the "great dying", the once-dominant dinosaurs disappeared, and mammals began diversifying. The combination of cosmic collision and subsequent environmental disasters, including the massive volcanic activity, played a critical role in this mass extinction event.
