       Macropoma is a specific genus of coelacanth.‭ ‬For clarification,‭ ‬a coelacanth is a word used to describe any fish that could be described as one of the Coelacanthiformes,‭ ‬but does not denote a specific species or genus.
       Macropoma is known to have lived during the‭ ‬late Cretaceous period,‭ ‬specifically around the Cenomanian and Turonian stages,‭ ‬though the full temporal range may well exceed this.‭ ‬Also,‭ ‬although Macropoma is most often associated with Europe,‭ ‬specifically England and the former state of Czechoslovakia‭ (‬now split into the Czech Republic and Slovakia‭)‬,‭ ‬though fossil remains are also now known from Africa‭ (‬Niger‭) ‬and South America‭ ‬(Brazil‭)‬,‭ ‬indicating a cosmopolitan distribution for the genus.
       The coelacanths are world famous as an example of creature that according to science was long extinct for tens of millions of years,‭ ‬only to be later found still alive and thriving in the deep waters of the Indian Ocean.‭ ‬Coelacanths that are alive today are classified under the Latimeria genus,‭ ‬and using these as a model it is possible to infer some living traits of the extinct Macropoma.‭ ‬If similar then Macropoma would have been deep water fish that spent the day lurking in caves and crevices,‭ ‬while emerging at night to hunt for other marine organisms on the sea floor.‭ ‬At fifty-five centimetres long however,‭ ‬Macropoma were quite a bit smaller than Latimera which are known to grow up to about one hundred and eighty centimetres long.
