Dippy, I made this diplodocus in blender to experiment with decimation maps and UV unwrapping, I'm very happy with the outcome but would like to develop it further.
The term Mesolithic derives from the combination of two Greek words:
mesos: in the middle
líthos: stone
The Mesolithic represents the era of the middle stone, marking the transition between the Paleolithic, the era of ancient stone, and the Neolithic, the era of new stone.
Dating and Duration
The Mesolithic began approximately 10,000 years ago, unfolding over a timeframe that concluded about 8,000 years ago. This period was characterized by significant environmental and behavioral changes.
Glacial Melting and Floods
One of the key events of the Mesolithic was the melting of glaciers, leading to an era of floods. This phenomenon resulted in a significant reduction of vegetation and caused the death of numerous animal species. This condition posed an increasing challenge for humans in sourcing food.
Transition to Agriculture and Animal Husbandry
With the growing difficulty in hunting wild animals and finding plant resources, humanity was compelled to innovate. In response to environmental challenges, humans began practicing animal husbandry and developed early forms of agriculture.
Abandonment of Nomadism and Sedentary Life
Gradually, humans abandoned the nomadic lifestyle, favoring a transition to a sedentary life. This behavioral change was motivated by the need to ensure a stable food supply through agriculture and animal husbandry.
Climate Changes and the Birth of the Neolithic
With the retreat of waters that had previously flooded the Earth, the climate became drier, creating more favorable living conditions. This marked the beginning of the Neolithic, an era characterized by further technological and social developments.
Conclusion: A Period of Fundamental Innovation
The Mesolithic emerges as a crucial period in human history, marked by environmental challenges that stimulated innovation and the transition to more settled ways of life, paving the way for the Neolithic and its subsequent evolutions.
🌍🦗 Journey to the Past: Earth in the Age of Giant Insects 🌿🦕

Imagine a world where insects ruled as giants, soaring through the skies and scuttling across the Earth's surface. This intriguing period, known as the Carboniferous era, is a fascinating chapter in our planet's history. Join us on a captivating journey as we explore what Earth was like during this age of colossal insects and lush forests.
🌿 The Carboniferous Era: A Verdant Paradise 🌿
During the Carboniferous era, which spanned from approximately 359 to 299 million years ago, Earth was vastly different from the world we know today. It was a time of lush, swampy forests, teeming with life and unique geological features.
🌳 Towering Tree Ferns and Giant Horsetails 🌾
One of the defining features of this era was the prevalence of towering tree ferns and giant horsetails. These plants, which could reach heights of up to 30 meters (98 feet), provided a rich habitat for a diverse array of creatures, including massive insects.
🦗 The Rise of Giant Insects 🐜
The high oxygen levels during the Carboniferous era, estimated to be around 35%, played a crucial role in the evolution of gigantic insects. Insects rely on the diffusion of oxygen through their bodies, and the higher levels in this ancient atmosphere allowed them to grow to unprecedented sizes.
🦋 Dragonflies the Size of Hawks 🌬️
One of the most iconic creatures of this era was the Meganeura, a colossal dragonfly with a wingspan of up to 75 centimeters (29.5 inches), comparable to that of some hawks. These giant insects ruled the skies, preying on smaller creatures.
🕷️ Enormous Arachnids and Millipedes 🕸️
Giant arachnids, such as the Arthropleura, a massive millipede-like creature, patrolled the forest floor. Some Arthropleura species reached lengths of over 2 meters (6.5 feet). While these creatures may evoke fear today, they were an integral part of the ecosystem during the Carboniferous era.
🌋 Volcanoes and Continental Drift 🌎
The Carboniferous era was marked by significant geological activity, including volcanic eruptions and the formation of Pangaea, the supercontinent that eventually gave rise to our modern continents. These geological events shaped the landscape and influenced the distribution of life.
🌪️ Climate and Extinction Events 🦠
Despite the lush forests and abundant life, the Carboniferous era was not without challenges. Periodic ice ages and climatic fluctuations led to several mass extinction events, reshaping the ecosystem and driving the evolution of new species.
🌍 The Legacy of the Carboniferous Era 🌿
Today, we can still see traces of the Carboniferous era in the form of coal deposits, which were formed from the accumulation of plant matter in the swampy forests. These coal deposits have played a significant role in shaping human history and industrialization.
Conclusion:
The Carboniferous era paints a vivid picture of Earth's ancient past, a time when giant insects and lush forests dominated the landscape. It reminds us of the ever-changing nature of our planet and the incredible diversity of life that has thrived throughout its history.

This remarkable find sheds new light on the diversity and evolution of tyrannosaurs, providing crucial insights into their morphology and adaptations. With a distinctively deep snout, this species adds to our understanding of the tyrannosaur family tree and their ecological niches.
Uncovering the secrets of prehistoric times! Recently, the world's largest dinosaur footprint at 1.7 metres was discovered in Kimberley, Western Australia. This remarkable find sheds light on the immense size of the dinosaurs that once roamed the Earth. Imagine standing next to a creature that left a footprint this huge!
We can learn so much about the past by studying these fascinating fossils. Stay tuned for more updates on our journey to uncover the mysteries of prehistoric life.
Taken 2021 16th November, my field trip took me to Stenbrottet i Hällekis. This was an Ordivician fossil site that had orthocones, most likely from 'Orthoceras regulare'. You don't even have to go to this site to find one, just looking at the stone floors of Sweden shows orthocones. #fossils #fossil #extinction #extinct #extinctanimals #extinctanimal #ordivician #prehistory #prehistoric #prehistoriclife #forhistorisk #invertebrate #invertebrates #bläckfiskar #orthocone #ordovicium #orthocones #blötdjur #mollusks #ortoceratiter #mollusk #animalia #mollusca #cephalopod #cephalopods #cephalopoda #orthoceratoidea #orthoceratidae #orthoceras #orthocerasregulare (at Stenbrottet I Hällekis) https://www.instagram.com/caseyunt2/p/CYYAfiPgU4n/?utm_medium=tumblr
