Parataxodium is an extinct genus of conifer that belonged to the subfamily Taxodioideae, [1] a group included within cypress family. [1] It is known primarily from fossilized remains dated to the Late Cretaceous period and is considered morphologically intermediate between modern genera such as Taxodium (bald cypress) and Metasequoia (dawn redwood). [1] One species is known, Parataxodium wigginsii. [1] [2] Although it belongs to the swamp cypress family, it inhabited a much wider range of environments, including the cooler regions of Alaska. [2] Although most fossils come from the Cretaceous, specimens are also known from both the Jurassic and the Paleogene. [3]

Distribution

Fossils are known from China, Canada and the United States (such as in Alaska, North Dakota and Montana).
