[22] [23] A study by Griebeler et al. (2013) concluded that the maximum growth rates of sauropodomorphs were comparable to those of precocial birds and the black rhinoceros but lower than the growth rates of average mammals. [23] A long-standing hypothesis has been that early sauropodomorphs were carnivorous, as expected for most early dinosaurs.
As for all dwarf species, their reduced growth rate led to their small size. [ 32 ] [ 51 ] Another taxon of tiny sauropods, the saltasaurid titanosaur Ibirania , 5.7 m (18.7 ft) long, lived a non-insular context in Upper Creaceous Brazil, and is an example of nanism resultant from other ecological pressures.
These results are consistent with the relationship between dinosaurs' sizes and growth rates (described above). [80] [81] Studies of the sauropodomorph Massospondylus and early theropod Syntarsus (Megapnosaurus) reveal growth rates of 3 kg/year and 17 kg/year, respectively, much slower than those estimated of Maiasaura and observed in modern ...
A study on bone histology of Trialestes romeri, providing evidence of a rapid growth rate, is published by Ponce, Cerda & Desojo (2025). [3]A study on the biodiversity of thalattosuchians throughout their evolutionary history, attempting to identify factors driving thalattosuchian evolution, is published by Forêt et al. (2025).
The growth line annuli are found compressed between broad vascularized regions of bone with randomly oriented fibrillar patterns, known as zones. Lines of arrested growth, similar to annuli, are found between zones are avascular. They are, however, much thinner, and have relatively fewer bone fibers by volume.
Plateosaurus followed a trajectory similar to sauropods, but with a varied growth rate and final size as seen in extant reptiles, probably in response to environmental factors such as food availability. Some individuals were fully grown at only 4.8 metres' (16 ft) total length, while others reached 10 metres (33 ft).
