This list of the Mesozoic life of Alabama contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Alabama and are between 252.17 and 66 million years of age.
 | This article needs attention from an expert in Palaeontology. The specific problem is: Several of the genus names appear to be invalid. E.g. Heteromorpha appears to be a suppressed name for an ammonite. (May 2018) |
