Most museums and books portray lots of dinosaur scenes, separated by millions of years. But what if all these diverse environments existed at the same time? That’s what we’d expect to find if we look at the Bible’s history . . . and the world today!

Zebras grazing contentedly on the Serengeti plain, a jaguar lounging on an ombu tree, a herd of water buffalo wading across the Brahmaputra River. The more we learn about the world around us, the more we are struck by the bewildering variety of landscapes and living things, woven together into a singularly beautiful picture that points to the One who wove it.

As David looked around him, it is no wonder he was compelled to sing aloud, “The heavens declare the glory of God.” In fact, he said the whole of creation seems to be unceasingly shouting about God’s glory for everyone to hear (Psalm 19:1–6).

Before the Flood, Noah and the earth’s other inhabitants must have seen God’s glory, too. Seeing these wonders, Noah surely sang songs of praise to his Creator. But Noah’s world was lost under the waters of the worldwide Flood; and over time, those early landscapes and their inhabitants—including tyrannosaurs, sauropods, and stegosaurs—faded from memory.

Then, two centuries ago, a handful of curious fossil hunters began to unearth startling clues about a staggering variety of long-forgotten animals and plants that once populated the earth. These finds set off a mad quest to retell their stories, a furious hunt that has never died down.

Different Starting Points, Different Views

Three successive sets of Flood layers, in particular, captured the popular imagination: Triassic layers, Jurassic layers, and Cretaceous layers. Each seemed to preserve a unique array of plants and animals that represents a distinct ecosystem full of various ferns, non-flowering plants called gymnosperms, small mammals, dinosaurs, and flying reptiles.

Every layer was different. For instance, Cretaceous layers contain Tyrannosaurus and Triceratops, while Jurassic layers contain Allosaurus and Stegosaurus.

Based on their faulty assumption that present-day slow processes have always been at work, early biologists interpreted the fossils in Triassic, Jurassic, and Cretaceous rocks as a series of communities that lived during different eras, separated by long periods of time. They believed each community replaced a previous community that had gone extinct. Each new community spread over much of the world before it also went extinct, to be replaced by another community.

Modern creationists, on the other hand, accept the Bible’s straightforward record of history. God created every kind of living thing in six days—only a few thousand years ago—and later He destroyed the earth in a worldwide Flood. Based on these facts, the same fossils can be interpreted as three different dinosaur communities living at the same time just before the Flood but at different locations. These communities were buried in succession, as each was overrun by rising Flood waters.

Clues from Present-Day Environments

What is the evidence that different environments existed at the same time? Perhaps a closer look at present-day environments would help.

Today we don’t find one big environment but many different environments, and sometimes they are very close to one another—even on the same mountain or island.

From Romans 1:20 we learn that the Creator made sure His “eternal power and Godhead” was clearly seen “since the creation of the world.” If the same Creator was on display in Noah’s day as today, we would expect to find familiar patterns in both worlds.

Everywhere we look, we see a pattern of immense diversity—and yet that variety is woven together into a tapestry of astonishing order and unity. Consider the immense variety of stars, planets, and atomic particles. Despite all this variety, they share many similarities and connections that we can readily discern.

Organisms are yet another example. God didn’t merely create a diverse array of organisms (bacteria, protists, algae, fungi, plants, and animals); He also created the potential for wide variety within each category, which remains orderly and understandable.

For example, among the plants we find tens of thousands of orchid species spread over the earth today, and among animals we find more than a quarter million beetle species. Despite all this variety, we don’t have a problem recognizing which plants are “orchids” or which animals are “beetles.”

The breadth of variety among organisms is far, far greater than can ever be explained by natural processes even after billions and billions of years of evolution,1 and the variety within each major group of organism is many times greater than is necessary for survival.2

To pack creation with such diversity requires careful design. To give all these organisms homes, God filled the earth with a variety of physical environments: some are of dirt, some of water, and others of air. Within each environment is more variety, including different temperatures, pressures, nutrients, and amounts of water. Then He designed organisms of different sizes, diets, and times of activity so that even more creatures could share the same environment.

Creating the same environment on different continents would allow even more variety. Consider, as one example, all the variety among modern grasslands (North America’s prairie, South America’s pampas, Africa’s savannah, Asia’s steppe, and Australia’s interior grasslands). North America and Asia have red foxes and gray wolves, while South America has maned foxes and wolves, and Africa has bat-eared foxes and African wild dogs (while Australia has marsupials). The variations could easily fill a book. North America has bald and golden eagles, South America has buzzard-eagles, Africa has martial eagles, Asia has steppe eagles, Australia has little eagles. . . .

Since creation abounds in unity and diversity, could this be part of God’s intended message through creation? God is both one and three—one God in three unique persons. Is the oneness and variety of the creation intended to showcase the Godhead’s delight in His own unity and diversity?

Environments Today . . .

The Creator has filled the earth with many different, wonderful environments, such as Africa’s Serengeti plain. Each has a unique combination of animals and plants, which can be readily identified. Amazingly, the pre-Flood world appears to have had a similar varienty of environments . . .

  Serengeti Plain Jurassic Cretaceous
Meat-Eaters hyenas, lions Allosaurus, Ceratosaurus Dromaeosaurus, Troodon, Tyrannosaurus rex
Plant-Eaters gazelles, giraffes,rhinoceroses, zebras Apatasaurus, Dryosaurus, Mymoorepalta, Stegosaurus Ankylosaurus, Edmontosaurus, Pachycephalosaurus, Triceratops
Small Mammals gerbils, mice Docodon, Priacodon Alphadon, Mesodma
Flyers martial eagles,other African birds Harpactognathus, Kepodactylus Avisaurus
Large Trees African acacia and boabab nonflowering gymnosperms (conifers and gingkos) seed-bearing angiosperms (sycamores and magnolias)
Mid-Size Plants cassia cycads laurels and magnolias
Small Plants grasses like Themeda ferns like Marattiales ferns like Dryopteris

Clues from Pre-Flood Environments

Despite the unity and diversity of modern ecosystems, remember that they are not the direct result of God’s original creation. The Flood’s judgment altered every environment of the original earth and exterminated most organisms. Yet God, the Creator and sustainer of the world (Colossians 1:17; Hebrews 1:3), oversaw the earth’s recovery following the Flood. Today’s abundant diversity and unity reflects that fact. God superintended as new physical environments were formed, as high diversity of organisms was generated anew, and as animals and plants settled in their proper environments.

If God restored the post-Flood world with such a variety of environments, then it would not be surprising if He placed at least as much variety in the pre-Flood world. But what would the unity and diversity of His original creation have looked like?

Evidence of the original variety appears to have survived the destruction and mixing of the global Flood. For instance, we have found fossils of over 17,000 trilobite species (an extinct crab-like creature with an outer skeleton) and about 2,500 nautiloid species (squid-like creatures in a shell; only the Nautilus survives).

The variations among plant species also indicate that they grew in a wide variety of climates. Variations in growth rings indicate climates ranging from cool temperate to tropical.3

The strange assortment of plants and animals indicates that some pre-Flood ecosystems were unlike anything we find today and did not survive the judgment of the Flood. This includes the trilobites’ various seafloor homes and perhaps a unique “forest” of hollow plants that once floated on the ocean (similar to quaking bogs today).4

Some other groups of creatures still have surviving representatives, but they are no longer as diverse or common as they were before the Flood. Examples include the Nautilus (nautiloids), lamp shells (brachiopods), sea lilies (crinoids), and large lobe-finned fish (coelacanths).

The loss of all this variety indicates that the diversity of the original creation—that which God directly created—was even greater than what we see in the present.

Jurassic Environment

A unique combination of plants and animal fossils is found in the Jurassic rock layers of the Morrison Formation (Dinosaur National Monument). They appear to represent a complete environment, like the Serengeti plain. If so, then this may be just one of many ecosystems that filled Noah’s world.

Animals and Plants in the Jurassic Environment

Meat-Eater: Allosaurus
Plant-Eaters: Apatasaurus, Stegosaurus, Dryosaurus
Small Mammals: Docodon
Flyers: Harpactognathus
Large Trees: gymnosperms
Mid-Size Plants: cycads
Small Ground Cover: ferns

Jurassic Environment

What About the Dinosaurs?

So what about dinosaurs? Based on the fossils found so far, they were a rather diverse group in pre-Flood times but now are extinct. The actual diversity was likely to have been even greater, since some organisms may not have left any fossils.

Dinosaurs didn’t live alone. A full set of plants, dinosaurs, and other animals are found in Triassic sediments. These fossils are distinct from those found in Jurassic rocks, and both are distinct from the organisms buried in Cretaceous rocks. So it appears that dinosaurs lived in a minimum of three ecosystems specifically designed for them.

You can easily see these distinctions when you compare the finds at two famous fossil locales. First is the famous “fossil wall” at Dinosaur National Monument in Colorado. Second is the source of most T. rex specimens: the Hell Creek Formation of Montana, Wyoming, and South Dakota.

The remains of these ecosystems share some striking similarities with present-day environments. Today we typically find lots of grasses, flowering trees, rodents, grazing mammals, carnivorous mammals, and birds. Each dinosaur layer preserves a similarly full ecosystem with ferns, gymnosperms, small mammals, flying reptiles, plant-eating dinosaurs, and meat-eating dinosaurs (which did not start eating meat until after Adam sinned).

Consider how similar these pre-Flood locales are to just one modern ecosystem—grasslands. Each has herbaceous plants, bushes, and trees. Each has plants for dry areas, wet areas, sun, and shade. Each has many tiny mammal herbivores, massive herb grazers (such as Triceratops and rhinoceros), long-necked tree grazers (such as sauropods and giraffes), meat-eaters (such as Allosaurus, Tyrannosaurus, and lions), and flying animals (pterosaurs and birds).

This is the kind of awesome similarity and variety we might expect if the same God who created the world continues to superintend the world so that His “eternal power and Godhead” are on display for all to see.

Cretaceous Environment

The combination of plants and animals in the Cretaceous rock layers of the Hell Creek Formation (Western U.S.) is very different from those in Jurassic rocks. Why? They may represent a completely different environment during Noah’s day. Both environments were then buried and preserved by the global Flood.

Animals and Plants in the Cretaceous Environment

Meat-Eater: Tyrannosaurus rex
Plant-Eaters: Edmontosaurus, Triceratops, Ankylosaurus
Small Mammal: Alphadon
Flyers: Avisaurus
Large Trees: angiosperms
Mid-Size Plants: laurels
Small Ground Cover: ferns

  1. Even if natural process could indefinitely generate new species at the rate suggested by macroevolutionary theory (the view that all of life evolved from a single organism, in contrast to the Bible’s teaching that God separately created every kind of creature in just six days), and even if this has been happening for billions of years (though it also cannot be true because it contradicts the Bible), there would still not be enough time to generate the disparity of life we observe on this planet. Back
  2. The fact that species are going extinct every day without whole ecosystems collapsing shows that the world has much more variety of organisms than is necessary for life to continue. And, since the primary driving process for biological change according to evolutionary theory (natural selection) takes out variety unnecessary for survival, the excess variety is a powerful evidence against evolutionary theory.

Even though earlier creationist ideas about a uniform pre-Flood climate have not stood the test of time, there is good reason to believe that the overall temperature of the earth was higher than the present, so the tropical and subtropical zones were much wider than at present and the temperate zone may have reached all the way to the poles.
