Did the t Rex have few glands in skin?

The T. rex, like other theropod dinosaurs, likely had skin with few glands, as evidence suggests that they had scaly skin similar to modern reptiles. While some modern birds, which are their closest living relatives, possess skin glands, the presence of such glands in T. rex remains uncertain. Most paleontological findings indicate that their skin was primarily adapted for protection and did not have many specialized glands. Overall, the specific glandular structures of T. rex skin are still a topic of ongoing research.
