Dinosaurs Lived With Mammals

According Genesis Chapter 1:24-25, all land animals were created on day 6 of the creation week. This would mean that dinosaurs and mammals lived at the same time.

In the past most evolutionary timelines have mammals evolving after reptiles. George Gaylord Simpson contended that, according to standard evolutionary theory, no advanced mammals were present in the “age of the dinosaurs.”

This is a logical explanation if you are going to contend that mammals evolved from reptiles, because it would require that mammals appeared much later in the picture.

However, the discovery of mammalian fossils has challenged such notions.


Fossil finds at Gippsland Beach(Flat Rocks), Australia, raised controversy about a long held evolutionary theory. This dinosaur rich fossil bed yielded placental type mammal fossils.

This group of mammals (according to evolutionary reckoning) was thought to arrive 5 million years ago; yet they lay next to dinosaur fossils that existed 115 million years ago. According to evolutionary theory, these mammals should not have been alongside roaming dinosaurs over the Australian landscape.

Paleontologist Tom Rich and his crew made the discovery. One volunteer from Flat Rocks said, "This has broken a culture of science. It proves that if you have a theory that you're holding onto it can change."


NewScientist reported in January 2005 a stunning fossil found in China which overturned preconceived ideas. Not only did large mammals live alongside their giant reptilian cousins, but some were big and bold enough to go dinosaur hunting.

Named Repenomamus giganticus; this was a sturdily built dog-like mammal.

Considering the specimen, scientists suggest the period in which these animals lived may have been much different than is commonly understood as the Age of Dinosaurs.

Scientists say that the animal's last meal probably is the first proof that mammals hunted small dinosaurs. It contradicts conventional evolutionary theory. It appears that at least some smaller dinosaurs had to look over their shoulders for snarling, meat-eating mammals claiming the same turf.

"This new evidence gives us a drastically new picture," said paleontologist Meng Jin of the AmericanMuseumof Natural History in New York City,NG January 2005


In 2004 scientists reported that they uncovered fossils of a swimming, fish-eating mammal that lived in China. The mammal lived well before it was thought that some mammals could have spent much of their lives in water.

The species appears to have been an amalgam of animals. It had a broad, scaly tail, flat like a beaver's. Its sharp teeth seemed ideal for eating fish, like an otter's. Its likely lifestyle burrowing in tunnels on shore and dog-paddling in water reminds scientists of the modern platypus.

Thomas Martin, at Senckenberg Research Institute in Frankfurt, said "This exciting fossil is a further jigsaw puzzle piece in a series of recent discoveries, demonstrating that the diversity and early evolutionary history of mammals were much more complex than perceived less than a decade ago."


Next door to the creation of land animals was the creation of birds on day 5 of the creation week. Recent examinations of an Antarcticafossil found in 1992 revealed evidence of a avian species called Vegavis iaai,  a close relative of modern-day ducks, chickens and geese. Vegavis iaai coexisted with dinosaurs according to fossil research compiled by professors at North CarolinaStateUniversity.

Considering the many times evolutionary theory has been completely contradicted by the evidence, it’s important to trust God’s authoritative word revealed in Genesis. The scientific evidence continues to support a special creation by an intelligent Designer.
