Caption: The Point Amour Patch Reefs / Les plaques de recif de Point Amour
Additional Description: The mound-like formations present along this shore are composed of the calcite skeletons of an extinct group of sponge-like animals called Archaeocyathids (arc-ae-o-sy-a thids). The Point Amour Arcaeocyathid reefs, which we formed 530 million years ago, provide evidence that this region was once in a warm shallow sea near the equator.
French:
Les formations arrondies le long de cette cote composent des squelettes calcifies d’un groupe d’animaux resemblant a l’éponge, aujourd’hui disparus nommes archaeocyatides. Les récifs archaeocyatides de Point Amour, qui se formèrent il y a environs 530 million d’années témoignent du fait que cette region était une fois un mer tièdes et peu profonde en proximité de l’équateur.
