The existence of follicles with a "super flat" epithelium and the large number of primary and especially secondary lysosomes and lipofuscin granules in these cells are characteristic features of the thyroid gland of adult marmosets (Callithrix jacchus, new-world monkeys). It is supposed that these morphological findings are indications of a relatively low function and early ageing.
