Study author Eva Griebeler challenges original T. rex estimate, revealing astonishing new findings.

Improved model corrects overlooked factors, reducing estimated number of T. rexes.

Charles Marshall, lead author of the original study, praises the more comprehensive research.

Complex model considered various variables to estimate T. rex population.

Disagreement arises over survival rates, egg-laying capabilities, and number of generations.

Updated model suggests a maximum of 1.7 billion T. rexes once roamed the Earth.

Original study driven by curiosity, now replaced with a "more realistic" estimate.

Mysterious scarcity of T. rex bones questions our understanding of their existence.

Ongoing research needed to uncover the truth behind the limited fossil discoveries.

Constantly evolving knowledge about T. rex challenges previous assumptions, revealing new insights.
