A pair of yolked oxen can pull 6-7.5 tons—enough to move the average 2.5-ton pyramid block. Müller-Römer's research supports this, noting ramps had 7-8° slopes 🐂🏛️

Key facts claimed:

- Average limestone block in Great Pyramid weighs 2.5 tons

- A single trained ox can pull 1 to 2.5 tons depending on terrain and training

- A pair of yolked oxen can pull 6 to 7.5 tons

- Researcher Müller-Römer's 2017 paper acknowledges oxen use and states transport ramps had 7-8° slope

- Archaeological evidence shows 4,000 lb of meat from cattle, sheep and goats were consumed daily at Giza during pyramid construction
