Exceptional discovery of marine shrimp remains (Crustacea decapoda) in the levels of the Roman harbour area of Ratiatum (Rezé, Loire Atlantique)

Abstract : Shrimp remains (Crustacea decapoda) have been discovered in programmed archaeological excavations in the Roman harbour area of Ratiatum (Rezé, Loire-Atlantique). Coming from two sets of shrimp remains dating from the first half of the 2nd century and from the first half of the 3rd century A.D., the parts of carapaces from these small animals can only be detected after carefully sieving about 20 litres of sediment with a 1,1 mm square mesh. The discovery of these shrimp fragments is exceptional at an archaeological site and their presence is linked to a good preservation in a damp environment. The morphology of the rostrum helps us to determine Palaemon longirostris with four spines under the rostrum whilst the morphology of the telson (the part at the rear end of the body of arthropods) makes the sand shrimp (Crangon crangon) clearly identifiable. The number of Palaemon longirostris rostrums (85) is quite considerable, nevertheless there are only three Crangon telsons. Biometrical relations (total lengths related to distance between tooth 1 and 4 under the rostrum) established from current-day shrimps help us to reconstitute the original lengths of the crustacea of Rezé by measuring the parts of the exoskeleton mentioned. The fact that pieces of shrimps are systematically associated with small fish used in preparing fish sauces suggests that these shrimps were probably used in this type of preparation too. The ecology of the main species Palaemon longirostris shows that they were caught in an estuary such as that of the Loire.
