Largest Land Animal-Titanosaur

Largest Land Animal
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.

Tyrannosaurus Rex, the Vulture

Tyrannosaurus Rex
We tend to view Tyrannosaurus rex as a 20-foot tall flesh eater who ran down its prey. Some have called this dinosaur “the most efficient carnivore who ever lived.” Science fiction movies like Jurassic Park have probably been the main source of this image, but the fact is that T. rex was nowhere near that fast.

Past studies of T. rex suggested that its huge mass–in the vicinity of nine tons–prevented it from running down much of anything. The muscle strength needed to accelerate that mass is simply not available to any form of life. Now simulations of acceleration and bone strength have verified that understanding. A speed of about 12 mph would have been the top limit for T. Rex and for only a short distance. That means a human could easily outrun a T. rex.

Tyrannosaurus rex was probably more of a scavenger than a hunter. There were other slow-moving dinosaurs such as Edmontosaurus, Triceratops, and Ankylosaurus that T. rex might have been able to catch. It is more likely that the T. rex population were the vultures of their day, not the lions of their day.

God created dinosaurs for a purpose, and every year we understand more about how they helped sustain the ecosystem that produced many of the resources we need. Every little boy seems to be fascinated with the media presentations of these creatures, but they really were not that glamorous.

Dinosaur Pseudoscience Part 2

Dinosaur Pseudoscience Fire-breathing
Yesterday we stated that one of the greatest challenges that this ministry faces is the bad science and false claims by creationists, including dinosaur pseudoscience. In addition to the ones we mentioned yesterday, another example is the claim of many creationists that dinosaurs were fire-breathing dragons.

In the Middle Ages, there were numerous stories about flying dragons who breathed fire. In recent years we have seen movies showing everything from Puff the Magic Dragon to How to Train Your Dragon as well as video games showing dragons that look like dinosaurs. Creationists have proposed that dinosaurs had hypergolic chemicals (chemicals that ignite when combined) that they used to produce literal fire. The scientific problems with such proposals are huge. Hypergolic chemicals are highly toxic to biological organisms. Fire going out of an animal’s mouth or nose would cause damage to the tissue. Atheists and biblical skeptics have written numerous articles showing the impossibility of these proposals on a scientific basis.

What is the biblical passage that creationists use to suggest that dinosaurs were fire-breathing dragons? The answer to that question is Job 41. The key word in this chapter is “leviathan.” The word is used three other times in the Bible–Psalms 74:14, Psalms 104:26, and Isaiah 27:1 In all of these references the leviathan is a sea creature. In other non-biblical Hebrew writings the word is used to describe a sea creature, and in a few cases, a sea crocodile is the translation. Job 41:18 says that when leviathan sneezes a light shines and his eyes look like the dawn. Verse 19 says that fire comes from his mouth and verse 20 says that smoke comes from his nostrils. This is poetic language and obviously doesn’t describe the animal anatomically. Verse 29 says that the leviathan laughs and verse 31 says that he makes the sea boil like a pot of ointment. These are obviously poetic descriptions of a very fierce sea creature. It is not a dinosaur living on the land, flying, and belching fire.

There is no valid fossil support for humans and dinosaurs living at the same time, and there is no biblical passage that states it. Cherry-picking a poetic description in Job to back up a denominational belief system is not taking the Bible literally.

Those of us who believe in God are in a war with forces who wish to destroy Christianity and the Bible. Pseudoscience used to defend a denominational understanding of a biblical passage just becomes a tool of those who despise Jesus Christ. It is a tool they use to destroy the faith of bright and well-educated young adults. We must not give them that tool.

Dinosaur Pseudoscience

Dinosaur Pseudoscience
One of the greatest challenges that this ministry faces is the bad science and false claims that are generated by creationists associated with various denominational groups. One of the challenges relates to dinosaur pseudoscience. History professor Ronald Numbers has shown that over 90% of creationist materials presented in this country are produced by dispensational and millennial groups who start with their denominational doctrines and try to shoe-horn science into their belief system. (Ronald L. Numbers, The Creationists, Harvard University Press, 2006.) We prefer to take the Bible literally.

Atheists and secular groups use the bad science involved to discredit the existence of God and the Bible as His word. The most basic problem presented by these creationist groups is that in spite of their claims, they do not take the Bible literally. By cherry-picking biblical statements, they attempt to make the Bible give a date to every event in the history of the Earth. They suggest that all 26-million different forms of life on the Earth today were present on the day of creation which they claim was roughly 6,000 years ago.

The fact is that the Hebrew words in Genesis were descriptions of animals that Moses knew and that his contemporaries had domesticated. Bacteria, viruses, platypuses, flightless birds, and countless sea creatures were not what Moses was referring to, and not what his readers would have understood him to be describing. For more on this go to and read the booklet titled God’s Revelation in His Rocks and His Word.

Perhaps the best example of creationist pseudoscience is their effort to explain the dinosaurs. We need to understand that none of the words used in Genesis 1 could reasonably be applied to dinosaurs. Creationists try to tell us there is scientific evidence that humans and dinosaurs lived at the same time. They point to a painting by the Kuku Yalanji tribe of Queensland, Australia, which shows an animal that looks like a plesiosaur. It turns out that the tribesman actually copied a painting from a children’s book called The Giant Golden Book of Dinosaurs published in 1960.

Another example of this kind of bad science is the claim that a Japanese fishing boat named the Zuiyo-Maru snagged a carcass of a dead plesiosaur in 1977. It was badly decomposed, and research has since shown that it was the carcass of a basking shark.

To say that humans and dinosaurs lived together defies many scientific facts and brings ridicule on faith in God. Perhaps the most laughable suggestion is to insist that there were fire-breathing dinosaurs. We will deal with that bit of dinosaur pseudoscience tomorrow.
