Comparing the Sizes of Dinosaurs in the Lost World

When dinosaurs inhabited the Earth over 66 million years ago, their sizes and species varied dramatically.

While geological evidence is far from complete, fossil evidence suggests that the largest dinosaurs were comparable to the length of a Boeing 737 or the weight of 12 elephants. Meanwhile, the smallest were similar to the size of a chicken or bird.

In this infographic from Giulia De Amicis we compare the sizes of dinosaurs to get a sense of their vast scale and diversity.

Sizes of Dinosaurs Compared to Modern Day Life

Towering as high as 39 meters, the Argentinosaurus or ‘Argentina lizard’ is currently thought to be the largest dinosaur ever discovered. It was a sauropod, a subgroup of dinosaurs with very long necks and long tails, four wide legs for support, and relatively smaller heads.

In 1987, its bones were unearthed in the Patagonia region of Argentina, a destination well-known for prehistoric fossils. For comparison’s sake, the length of the Argentinosaurus is as high as a 13-story building.

Nature Timespiral: The Evolution of Earth from the Big Bang

Since the dawn of humanity, we have looked questioningly to the heavens with great interest and awe. We’ve called on the stars to guide us, and have made some of humanity’s most interesting discoveries based on those observations. This also led us to question our existence and how we came to be in this moment in time.

That journey began some 14 billion years ago, when the Big Bang led to the universe emerging from a hot, dense sea of matter and energy. As the cosmos expanded and cooled, they spawned galaxies, stars, planets, and eventually, life.

In the above visualization, Pablo Carlos Buddassi illustrates this journey of epic proportions in the intricately designed Nature Timespiral, depicting the various eras that the Earth has gone through since the inception of the universe itself.

Evolutionary Timeline of the World

Not much is known about what came before the Big Bang, but we do know that it launched a sequence of events that gave rise to the universal laws of physics and the chemical elements that make up matter. How the Earth came about, and life subsequently followed, is a wondrous story of time and change.

Let’s look at what transpired after the Big Bang to trace our journey through the cosmos.
