Because the rocks of the range were formed in an ancient seabed, the Brooks Range contains [[fossil]]s of [[marine organism]]s. In addition to the [[coral]] fossils shown, [[trilobite]]s and [[brachiopod]]s from the middle [[Cambrian]] have been found in the sandy [[limestone]]s of the Central Brooks Range.<ref>J.T.

During the middle of the Cretaceous, the Brooks Range thrust belt underwent significant regional extension.<ref>{{Cite journal |last=Miller |first=Elizabeth L. |last2=Hudson |first2=Travis L. |date=August 1991 |title=Mid-Cretaceous extensional fragmentation of a Jurassic-Early Cretaceous Compressional Orogen, Alaska |url=http://doi.wiley.com/10.1029/91TC00044 |journal=[[Tectonics (journal)|Tectonics]] |language=en |volume=10 |issue=4 |pages=781–796 |doi=10.1029/91TC00044 |access-date=30 September 2023|url-access=subscription }}</ref>

Remains of a [[woolly mammoth]] that died about 17,100 years ago were found north of the Brooks Range. A research report on its movement range was published in 2021.<ref>[https://www.theguardian.com/science/2021/aug/12/woolly-mammoth-walked-far-enough-circle-earth-twice-study Woolly mammoth walked far enough to circle Earth twice, study finds]. theguardian.com 12 Aug 2021</ref>
