Part I: Summary The Christian community has many questions about the origin and existence of dinosaurs. While some may think these questions are foolish, there is a lack of knowledge among Christians that needs to be addressed. This series is a rather meager attempt to address those questions, while providing information that will be beneficial to those who are more knowledgeable on this topic.

Taming the T-rex …And other dinosaurs CHALLENGING EARTH HISTORY: Part IV The Biblical Questions + Elaine Kennedy, Ph.D. Geoscience Research Institute
Does the Bible Talk About Dinosaurs?
Job 41:8,15, 29, 31 If you lay a hand on him [leviathan], you will remember the struggle…. His back has rows of shields tightly sealed together…. A club seems to him like a piece of straw; he laughs at the rattling of the lance…. He makes the depths churn… and stirs up the sea…. NIV
Job 40:15, 17, 21 Look at the behemoth… which feeds on grass like an ox. His tail sways like a cedar; the sinews of his thighs are close-knit. Under the lotus plant he lies, hidden among the reeds of the marsh. NIV
Were Humans & Dinosaurs Living Together?
What Are Some of The Questions Christians have about Dinosaurs?
Weren’t Dinosaurs too Big for the Ark? One Christian author says: Soon after the flood the race began to rapidly decrease in size, and in length of years. There was a class of very large animals which perished at the flood. God knew that the strength of man would decrease, and these mammoth animals could not be controlled by feeble man. EGW: 4A SG 121
Weren’t Dinosaurs too Big for the Ark? As we have seen, ½ the families of dinosaurs were smaller than an adult giraffe. So there is no reason to think that they might not be on the Ark. Perhaps the author is talking about the large mammals, reptiles, amphibians, insects, etc. that went extinct during the Flood. The extinction of large animals seems to be a consistent trend in the fossil record.
Were Dinosaurs Amalgamations? One Christian author says: Every species of animals which God had created was preserved in the ark. The confused species which God did not create, which were the result of amalgamation, were destroyed by the flood. EGW: 1SP 78
Were Dinosaurs Amalgamations? This author specifies that amalgamated species were considered “confused species.” There is nothing confusing about dinosaurs. Their bone structure is distinctive, their skeletal features are distinctive and when the data is studied, dinosaurs are a clearly defined group of animals.
Part IV: Summary What does the Bible say about dinosaurs? –Job 40 (large herbivore, probably low to the ground, probably not a dinosaur) –Job 41 (marine creature, not a dinosaur) What are some of the other questions about dinosaurs? –4A SG 121 (large animals, not just dinosaurs) –1 SP 78 (amalgamated, probably not dinosaurs)
Taming the T-rex …And other dinosaurs CHALLENGING EARTH HISTORY: Part V The Nests Elaine Kennedy, Ph.D. Geoscience Research Institute
Problematic Issues I: Dinosaur Eggs Are the dinosaur egg sites really nests?Are the dinosaur egg sites really nests? Are there multiple levels of dinosaur nests and eggs?Are there multiple levels of dinosaur nests and eggs? Are these sites pre-Flood, Flood or post-Flood deposits?Are these sites pre-Flood, Flood or post-Flood deposits?
Data: Oviraptor Eggs Mongolia Possible Overbank Deposition Some Nests Promising
Data: Maiasaur Eggs “Nest in Camp” Montana Eggs & fragments indicate transport Sediments indicate no nest here
Data: Troodon? Eggs Egg Mountain Two layers found here Limited documentation
Possible Nest Six eggs encased in plaster Note: “Rim” Carbonate rock
Data: Eggs in Patagonia Multiple levels of eggs Fragment orientations & distributions Cross-bedded sandstones
Data: Sauropod Eggs Lerida Egg Site Sediments indicate transported eggs
Data: Dinosaur Eggs Aix-en-Provence Crushed eggs with internal shell fragments Photographed by Elaine Kennedy near Montagne Sainte-Victoire, France
Data: Dinosaur Eggs South Korea Sediments suggest transported eggs Multiple levels
Part V: Summary In the literature, authors cite single and multiple eggs as “nests.” Regions estimated to have hundreds of eggs are considered nesting grounds. Little work has assessed the nature of the sediments in which the eggs were deposited. Consequently, there is little evidence for dinosaur nesting behavior.

Part VI: Summary The evolution of dinosaurs into birds is a popular theory. The postulated evolutionary evidence for links between dinosaurs and birds has been disputed by a number of credible researchers in paleontology and biology.

Best specimens purchasedBest specimens purchased
Part VII: Summary The validity of the feathers on dinosaurs is still debated; however, if the feathers are real, their presence on dinosaurs does not establish a link between dinosaurs and birds because true birds are found in lower layers with no ancestral evidence in the layers below.
Conclusions Dinosaurs lived on earth, probably created by God as unique organisms, “normal” existence Eggs and babies are genuine –Nests are not yet clearly established –Transport of eggs is widespread Feathered dinosaurs are considered links by some scientists –Feathers disputed –Links disputed
