5th modern vertebra (5 years; figure A) and 4th archaeological vertebra (4 years; figure B) of tadpole codling (Salilota australis) in the Strait of Magellan (Chilean Patagonia). We can note the growth rings on both figures. 

 

These figures are part of a work describing sclerochronological analyses of tadpole codling (Salilota australis) vertebrae as a proxy for the seasonal timing of fishing activities at one Middle Holocene (6500 BP) and three Late–Middle Holocene (3500–2500 years BP) archaeological sites located in Seno Otway and in the central zone of the Strait of Magellan, Chile.
