   • 1971, Acta Anatomica: Supplementum - Volumes 58-62, page 65:

     The loss of the internal carotid artery in the sciuroids seems likewise to go back to the early Tertiary. The oldest known sciuroid, Protosciurus (table XII) , stems from the Middle Oligocene [BLACK, 1963) , and the earliest sciuroids presumably evolved from central members of the paramyid group around the transition between the Eocene and Oligocene [WOOD, 1959].

   • 2012, Morris Goodman, Molecular Anthropology, page 192:

     It may also be noted that the fossil record stretches back no farther than the Oligocene on macroscelidoid elephant shrews (Patterson, 1965), also on sciuroids (Black, 1963), and no farther than the Miocene on lorisoids (Walker, 1974) .

   • 2013, W. Patrick Luckett, ‎Jean-Louis Hartenberger, Evolutionary Relationships among Rodents, page 347:

     These findings are contrary to the opinion that sciuroids are relatively archaic forms, based on their cuspidate dentition.

     In studying the early development of the sciuroid rodent Citellus the writer noted the following described conditions which may be of interest to investigators working on that yet unsolved problem of the origin of the vascular system.

   • 2018, Frank Zachos, ‎Robert Asher, Mammalian Evolution, Diversity and Systematics, page 217:

     In overall habitus, Maiopatagium is most comparable with the sciuroid gliding rodents with similar proportions of the propatagium, plagiopatagium, and uropatagium (Fig. 6.25).
