The plates on the back of a Stegosaurus were used as protection against predators.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the plates on the back of a Stegosaurus were used as protection against predators?

No. Scientific literature refutes the idea that Stegosaurus plates were primarily used as protective armor, pointing instead toward functions like thermoregulation and display.

Verdict: REFUTED · 0 sources for, 3 against · Last checked

The analysis

The retrieved literature consistently notes that traditional armor hypotheses for Stegosaurus plates are falsified by histological evidence showing thin walls and extensive vascular networks. Instead, studies like Mainelli (1986), Farlow et al. (1976), and Saitta et al. (2011) point toward thermoregulation and display, while reserving defensive weapon functions for the spikes rather than the plates.

Growth and function of <i>Stegosaurus</i> plates: evidence from bone histology
1986
Histological analysis of Stegosaurus dorsal plates indicates that while some functional interpretations like armor are falsified, thermoregulatory functions remain more robust.

2011
Ontogenetic histological analysis indicates that the extensive vascular networks of plates point toward display or thermoregulation, whereas defense functions belong to the spikes.
