Holtz estimated that Utahraptor existed between 130 million and 125 million years ago. This is supported by the presence of charred spores and other carbonized plant debris in the pollen maceral that indicate the occurrence of ancient wildfires ignited during periods of low precipitation.

Although this spelling has been largely used by other authors, the genus Utahraptor was originally coined with the type species U. ostrommaysi and given that the International Code of Zoological Nomenclature offers no provision for forming a genitive form from two persons with different names, Costa and Normand conclude that the original spelling ostrommaysi has to be regarded as an arbitrary combination of letters and not a correctly formed genitive form.
