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). ^{[3] [2]}
