Supernovae are cataclysmic explosions that occur during the last evolutionary stages in the life of massive stars.
Latest study supports the idea that the asteroid impact 66 million years ago was the main driver of dinosaur extinction, not intense volcanic activity as some have suggested.
The largest of these prehistoric species was 10 times the length of anchovies living today.
Scientists say the environmental changes that took place in the end-Triassic extinction event could be similar to what is predicted for the near future.
The extinct animal may reveal how modern birds survived the asteroid that wiped out large dinosaurs.
"We are beginning to transition and go through the extinction," study author David Gruber said. "Who comes out the other side is up for grabs."
248 million-year-old fossils discovered in Russia almost 60 years ago re-examined by scientists.

A study has reconstructed the immediate aftermath of the asteroid 66 million years ago to learn more about the impact of the momentous event.
Huge changes to the oxygen levels on our planet caused the mega die-off, researchers found.
Plant extinctions endanger other organisms, ecosystems and the ability of humans to survive on our planet.
Study suggests weakening of the field resulted in reduced protection from UV rays, leading to mammalian extinctions on Earth.
The research could help scientists understand natural disasters like landslides.
But if we act now, conservation efforts could save "billions of years of unique evolutionary history," scientists say.
