Dinosaurs: Time and Geological Scales

Time and the Geological Scale

The Chronological Framework — One World, Two Calendars

The debate over dinosaurs isn’t actually about the bones we find in the dirt; it is about the “clock” we use to date them. When we look at the history of the earth, we are choosing between two fundamentally different calendars. Mainstream science uses a vertical timeline of “Deep Time” where layers represent millions of years of succession. However, the Young Earth model uses a horizontal timeline where those same layers represent simultaneous habitats and ecological zones.

The Conflict of Scales

Mainstream geology relies on Uniformitarianism, the assumption that the slow, gradual processes we see today—like a river depositing a tiny bit of silt—have always happened at the same rate. This stretches the history of dinosaurs into a Mesozoic era occurring 66 to 252 million years ago. But the Young Earth model operates on Catastrophism. This suggests that the majority of the geological record was formed by high-energy, rapid events. In this view, the “Eras” aren’t periods of time; they are biomes. Dinosaurs didn’t live in a different time than humans; they lived in a different place—tropical, low-lying marshes—while humans occupied cooler, upland regions. This means that humans and dinosaurs did not live millions of years apart in time but rather hundreds of miles apart at the same time. This will be covered more in depth when we discuss the layering of fossils. 

The Assumptions of Radiometric Dating

Radiometric dating is often presented as an absolute proof of age, but it relies on several unprovable assumptions: that we know the initial amount of parent and daughter isotopes, that no contamination occurred over millions of years, and that decay rates have always been constant. If the earth experienced a massive tectonic and volcanic upheaval during a global Flood, these decay rates could have been drastically accelerated. Under such high-energy conditions, what looks like millions of years of atomic decay to a modern scientist could actually have occurred in a very short window of time. Since the geologic timescale is determined based on radiometric dating, the measurement of time may be drastically different in reality.
