Pleistocene Survival: How Would Humans Interact with Mesozoic Theropods?

In the vast expanse of Pleistocene history, when humans were part of the Paleolithic era, the dominant lifeforms were quite different from today's fauna. The Mesozoic era, known as the Age of Dinosaurs, had long passed. However, intriguingly, if we were to imagine a scenario where Pleistocene humans were co-existing with the remnants of Mesozoic Theropods, how might they have interacted?

The surviving Mesozoic Theropods, or carnivorous dinosaurs, were indeed more like mammals in size and dietary habits. Not as titanic as their ancestors, these creatures managed to co-exist with the rapidly evolving mammals, including early humans. However, these dinosaurs did get bigger again and started incorporating more plant matter in their diet, much like omnivorous mammals.

Yet, the question arises: would these humans have the opportunity or inclination to make these carnivorous, albeit smaller, animals miserable? Let's delve into this fascinating scenario.

The Context

In the Pleistocene epoch, around 2.6 million to 11,700 years ago, when our early ancestors roamed the Earth, the landscape was vastly different. While the Earth was cooler and experienced repeated glacial cycles, it was also a time of enormous biodiversity. Mammals were diverse and small in comparison to the colossal dinosaurs that had ruled the Mesozoic era. The largest mammals were the mammoths and saber-toothed cats, like the Smilodon, while the direwolf was a predominant canine predator.

However, a speculative thought experiment imagines a world where these humans had to face the more dangerous Mesozoic Theropods. These creatures, like the now-extinct Velociraptor and Allosaurus, were naturally carnivorous and posed a significant threat to early humans.

The Role of Competition

Competition with other mammals would have been a more immediate and pressing issue for early humans. The Smilodon and the direwolf were indeed prominent predators in their own right. Smilodon, with its formidable fangs, and direwolf, with its sharp teeth and powerful jaws, were fierce competitors for resources with early humans.

As early humans evolved, they developed sophisticated tools and social structures that allowed them to adapt to their environment. However, these skills were primarily directed towards surviving against other predators and adapting to the changing climate rather than making smaller theropods miserable.

The Interaction Hypothesis

Given the size and nature of these Mesozoic Theropods, it is unlikely that early humans would have had the resources or technology to make them miserable. They would have needed to focus on their own survival. The large, carnivorous dinosaurs, even if they had adapted to include plant matter in their diet, would still pose a significant threat to early humans.

Early humans would have had to coexist in a delicate ecosystem. Using their instinct and early tools, they could have tried to avoid these dangerous creatures, use natural defenses like caves for shelter, and even engage in opportunistic hunting and scavenging. However, making such smaller, albeit carnivorous, dinosaurs miserable would have been far beyond their capabilities.

The Broader Implications

Understanding how early humans might have interacted with these creatures can provide insights into their evolutionary journey and coping mechanisms. It also highlights the complexity of coexistence with formidable predators and the challenges faced during the Pleistocene. This thought experiment also reflects the adaptability of early humans, who managed to coexist and thrive despite numerous environmental and predatory challenges.

In conclusion, while the scenario of humans making miserable the carnivorous Mesozoic Theropods is intriguing, it is improbable given the realistic constraints of their abilities at the time. Early humans focused more on survival against other predators and adapting to their environment. This thought experiment serves as a fascinating exploration of our evolutionary history and the challenges faced by our ancestors.
