There would have been a huge temperature drop
The meteorite collision at the end of the Mesozoic era led to widespread fires, dust, and debris in the atmosphere, resulting in a significant temperature drop and altered sunlight reaching the Earth's surface. This caused a mass extinction event, including the extinction of the dinosaurs and about 75% of all species, leading to significant changes in the Earth's biosphere and ecosystem dynamics.
The meteorite collision at the end of the Mesozoic era caused significant changes in the atmosphere by releasing immense amounts of debris and gases that led to global cooling and darkening of the skies, disrupting photosynthesis and causing mass extinctions. The biosphere was greatly impacted as the sudden environmental changes wiped out around 75% of all species, including dinosaurs, and allowed for the rise of new species and ecosystems in the following Cenozoic era.
During the Mesozoic era, which lasted from about 252 to 66 million years ago, the atmosphere was characterized by higher levels of carbon dioxide, approximately 1000 to 2000 ppm (parts per million) compared to current levels of around 400 ppm. Oxygen levels were also higher, ranging from 26% to 30% compared to the current 21%.
The Mesozoic Era is also known as the Age of Reptiles.
It was part of the Mesozoic Era.

meteorite collision
paleontologists think but nobody knows its just a theory
The Chicxulub impact crater in the Gulf of Mexico is the most likely suspect for the meteorite impact that caused the Mesozoic extinction. The crater is 180 km in diameter, suggesting that the impacting body was approximately 10 km in diameter.
Yes, the atmosphere was more than adequately oxygenated for life in the Mesozoic.
The end of the Mesozoic Era is marked by the mass extinction event that wiped out the dinosaurs, known as the Cretaceous–Paleogene extinction event. This event was likely caused by a combination of factors, including a meteorite impact and volcanic activity, and led to significant changes in Earth's ecosystems.
The likely contributors to the extinction event marking the end of the Mesozoic Era, known as the Cretaceous-Paleogene (K-Pg) extinction event, include a large asteroid impact on Earth, massive volcanic activity, and climate change. The asteroid impact at Chicxulub in present-day Mexico is considered a primary factor, causing widespread devastation and leading to the decline of many species, including the dinosaurs.
http://en.wikipedia.org/wiki/Mesozoic Btw, it's not the Mesozoic "area" but the Mesozoic era. Hope this was helfpul!
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
Paleozoic - climate change Mesozoic - meteor
