Isolated teeth thought to be from the genus have been found from Florida and South Carolina and are of early Pliocene age. This was thought to be evidence of the interchange between North and South American faunas, with the genus first appearing in North America and then migrating down into Colombia and Brazil. This theory is no longer accepted, although the presence of " Charactosuchus" from Jamaica may suggest a European origin, with the genus migrating across either the De Geer or Thule land bridges.
