The first week of August a report was made in the Proceedings of the Royal Society B: Biological Sciences of perhaps the largest land animal that ever existed.
This dinosaur, found in Patagonia, Argentina, is named Patagotitan mayorum. It was more than 120 feet (36.5 m) long and weighed more than 76 tons (69 tonnes). It is also one of the most complete fossils with 150 bones recovered. When it is reassembled, the skeleton will be roughly the size of a Boeing 737.
What scientists want to learn about an animal of that size is, “How could it get so big?” We recently published a post about the world’s largest snake, the titanoboa. Reptiles, unlike mammals, continue to grow during their entire lives. In this case, the question is, “What sustains such massive growth?” How much food must the animal eat? How would its vascular system work? What is its significance to the ecology of the area where it lived? What environmental temperature and oxygen levels would allow an animal of that size to live? How could a human exist in such surroundings? Some of these questions are being addressed. Some are so complex that researchers on the site say it “is really hard to imagine” the answers.
We have pointed out that the ecological system that produced the resources humans would need to exist on this planet had to be different from what we have today. Those conditions would be hostile to human survival. This fossil of the largest land animal supports that point very well.

It was the world’s largest snake. Fortunately, it is extinct. The computer-generated picture shows what it might have been like if a human had ever confronted a Titanoboa (Titanoboa cerrejonensis).
One thing that many creationists and evolutionists forget is the fact that Earth’s climate in the past was much different from what it is today. To produce animals of massive size, Earth’s climate would have to be much warmer. The temperatures would have been so high that mammals could hardly survive. Cold-blooded (ectothermic) animals in tropical areas today tend to be larger than ectothermic animals found farther from the equator.
While giving lectures in Colombia, South America, we learned about the snake named Titanoboa. Fossils of more than two-dozen of these snakes were discovered in coal mines in northern Colombia. The name means “titanic boa,” and that seems fitting because it measured 48 feet (14.6 m) long and would have weighed 2500 pounds (1,135 kg). For a snake of that size to live, the climate must have averaged 90 degrees F (32 degrees C). It is difficult to comprehend how any mammal, especially humans, could survive in such temperatures.
Why would God have given this planet such an extreme climate? It was needed to support the world’s largest snake, other huge animals, and the massive vegetation they required. What was the purpose of those animals and plants? That environment made possible the coal, petroleum, and other resources that would later be needed by humans to support an advanced civilization. This is one more indication that the prehistory of the Earth had conditions uniquely designed by God to prepare the planet for human habitation.
