Dinosaurs Under the Seabed – No, This Is NOT New Evidence Shaking Up Evolutionary Theory

Claims that dinosaur fossils found on the ocean floor consтιтute “new evidence” that undermines the theory of evolution are misleading and scientifically unfounded.

Every verified dinosaur bone recovered from marine sediments — whether the Plateosaurus phalanx at 2,256 metres beneath the North Sea, theropod fragments from the deep Pacific, or isolated bones from the Gulf of Mexico and Mediterranean — is fully consistent with established palaeontology and geology. These specimens reached the seafloor through well-understood processes:

• Dinosaurs were strictly terrestrial animals.
• After death, carcᴀsses near rivers or coastlines were transported offshore by normal flooding and storms.
• Bodies sank into marine mud and were buried alongside fish, ammonites, and other marine life.

Over tens to hundreds of millions of years, continuous sedimentation and tectonic subsidence buried the remains kilometres deep.
No anatomical, isotopic, or sedimentological evidence supports the idea that non-avian dinosaurs lived in the sea. All complete, articulated skeletons and the vast majority of fossils come from terrestrial or coastal-plain deposits. The rare marine occurrences are always fragmentary and show clear signs of post-mortem transport.

These finds do not challenge evolutionary theory. On the contrary, they reinforce it by illustrating how dynamic Earth’s surface has been — rivers, sea-level changes, and plate tectonics routinely move terrestrial remains into marine environments. Science actively studies every such specimen because they provide valuable data on ancient coastlines and taphonomy.

From the North Sea to the Pacific abyss, the “dinosaurs under the seabed” story remains a fascinating demonstration of geology, not a crisis for evolutionary biology. The theory of evolution continues to stand on an overwhelming body of evidence from multiple independent fields — genetics, comparative anatomy, the fossil record on land, and molecular biology — none of which is threatened by these deep-sea fragments.
