Yes, there were already giant squids in the Cretaceous period. Fossil evidence suggests that large squids, similar to modern-day giant squids, existed during this time. These ancient squids likely roamed the oceans alongside other prehistoric marine creatures. The presence of giant squids in the Cretaceous period indicates that these fascinating creatures have been around for millions of years. **

Yes, the Allosaurus lived during the late Jurassic period, which was before the early Cretaceous period. Allosaurus was a large theropod dinosaur that roamed North America around 155 to 150 million years ago. By the time the early Cretaceous period began, Allosaurus had already become extinct. **

It is unlikely that humans could have survived in the Cretaceous period with the changed atmosphere. The atmospheric conditions during the Cretaceous period were significantly different from what humans require to survive. The high levels of carbon dioxide and other gases in the atmosphere would have made it difficult for humans to breathe, and the extreme temperatures and different plant and animal species would have posed additional challenges for human survival. Overall, the conditions in the Cretaceous period were not conducive to human life as we know it today. **

It is unlikely that humans could have lived in the Cretaceous period with the significantly different atmosphere that existed during that time. The atmosphere during the Cretaceous period had much higher levels of carbon dioxide, which would have made it difficult for humans to breathe. Additionally, the climate and environmental conditions during the Cretaceous period were very different from what humans are adapted to, making it challenging for them to survive. Overall, the changed atmosphere of the Cretaceous period would have presented numerous obstacles for human life. **

It is unlikely that humans could have survived in the Cretaceous period with its changed atmosphere. The atmosphere during the Cretaceous period had much higher levels of carbon dioxide, which would have made it difficult for humans to breathe. Additionally, the climate was much warmer and sea levels were higher, which would have made it challenging for humans to find suitable habitats and resources for survival. Overall, the environmental conditions during the Cretaceous period would have been inhospitable for human survival. **

Bats did not have a direct role in the extinction event that occurred in the Cretaceous period. The extinction event, known as the Cretaceous-Paleogene extinction event, is widely believed to have been caused by a massive asteroid impact, which led to the extinction of the dinosaurs and many other species. Bats, as we know them today, did not appear until after this extinction event, during the early Eocene epoch, which was around 50 million years ago. Therefore, bats were not involved in the extinction event that occurred during the Cretaceous period. **
