Pleistocene Humans and Cretaceous Predators: An Improbable Encounter
Imagine if Pleistocene/Paleolithic humans found themselves suddenly transported to the Cretaceous period. Would they manage to survive amidst the fierce and formidable theropods that roamed the ancient world, such as Tyrannosaurians, Spinosaurians, Therizinosaurians, Dromaeosaurians, and various birds of prey? Let us explore this intriguing scenario by examining the capabilities and vulnerabilities of both humans and dinosaurs during these vastly different periods.
Paleolithic Humans and the Cretaceous Epoch
The Paleolithic era marked the beginning of modern humans, Homo sapiens, who appeared around 300,000 years ago, though their hominin ancestors date back to about 2.1 million years ago. The Cretaceous period, on the other hand, lasted from 145 to 66 million years ago. Dinosaurs, especially the dramatic and formidable ones like Tyrannosaurus Rex, Spinosaurus, and Velociraptor, dominated this era. The last of the non-avian dinosaurs perished 66 million years ago, long before homo sapiens even existed.
Tyrannosaurians: Predators of the Cretaceous Period
Let’s first address the habitats and behavior of Tyrannosaurus Rex and its relatives. In a hypothetical scenario where these humans encountered such predators, they would likely be in a forest that resembles our current ecosystems. The presence of T. Rex would be a significant threat. These enormous creatures, with their estimated length of up to 40 feet (12 meters) and weight of around 6-7 tons, would instantly recognize us as small, unthreatening prey. However, their hunting strategies typically involved targeting much larger prey. While they might occasionally kill a human, they would mostly ignore smaller, more numerous, and less nutritious targets.
Raptors: Predators with Pack Tactics
Contrastingly, Raptors like Dakotaraptor and Velociraptor posed a far more immediate and dangerous threat. These smaller but intelligent and pack-hunting theropods would recognize humans as a potential food source. Relying on ambush strategies and coordination, a small group of Raptors could do significant harm to a human hunting party. The Terminus Rex (T. Rex) would likely sweep aside any disruptions in its environment but Raptors would not hesitate to attack and kill any human that posed a threat.
Therizinosaurs and Triceratops: Herbivorous Giants
While Therizinosaurs and Triceratops were herbivorous giants, they could also pose risks to humans. If Triceratops felt threatened or if a human encroached upon its territory, it might counterattack. However, for the most part, these massive herbivores would likely ignore small, unthreatening humans. Nonetheless, the potential for confrontation exists, especially if resources or territory were contested.
Terror Birds and Birds of Prey: Extinct and Still Prowling
Now let's consider the terror birds, also known as Phorusrhacidae. These extinct birds lived possibly up until 1.8 million years ago, but they were confined to South America and did not coexist with early homo sapiens, who lived entirely in Africa. Therefore, there was no overlap in their existence, and humans had no contact with terror birds.
Finally, we have the modern birds of prey, such as eagles, ospreys, hawks, buzzards, vultures, and falcons. While they are formidable hunters, they are significantly smaller than humans and pose no real threat to adults. However, incidents of larger birds attacking very small children have been reported. These birds, which have been around since approximately 18 million years ago, can be deterred from hunting by human activity. Although they may not fully grasp the nuances of fear and anger, humans can certainly thwart their attempts to hunt.
Conclusion
In conclusion, the encounter between Pleistocene humans and Cretaceous predators like Tyrannosaurians, Spinosaurians, Therizinosaurians, and Dromaeosaurians (including Raptors) would not have been conducive to human survival. However, the presence of terror birds and modern birds of prey would not have posed a significant threat, especially considering the small size of these predators.
