They also found that the remains of neonates, juveniles, and adults were clustered together, suggesting that Mussaurus may have split up into age-specific groups in their herd.
Living in herds likely gave sauropodomorphs an evolutionary advantage, the researchers say.
Because they lived and foraged closely together, Mussasaurs wouldn’t have needed to expend as much individual energy to find sustenance while travelling long distances.
That likely led to their body size getting larger over time.
