Found in archaeological context (500 AD), central coast of Chile.

paper of Chile scientists about otoliths-their contact details are included in the paper http://www.scielo.cl/scielo.php?pid=S0718-19572013000300019&script=sci_arttext
a digital database for otoliths, available online. http://digital.csic.es/bitstream/10261/5830/1/aforo.pdf
You should contact Dr. Sophia Perdikaris at CUNY Graduate Center, she is an otolith expert. If you google her coordinates are the first on the list and you can locate her email through that website.
No, they are not fish otoliths. They may be pharyngeal tooth plates, as they appear to have a tooth bed on one part.
A scale bar in the photo would have been helpful. I agree with Thomas, they most probably are pharyngeal teeth. You'd best consult a marine biologist.
Sorry about the scale. The larger is 8 mm. Pharyngeal teeth !
The size would fit in with the finds I know from Europe, but having no experience with South-American fishes, I haven't got a clue which species they could belong to.
Hola Rengert: any family to compare with our fish (central coast of Chile, South Pacific)
Hola Maryam,
Not fish otoliths but fish pharyngeal teeth from unknown species !
A fishermen from Easter Island told me he was bite very hard when he introduced his fingers thru the galls of 2 species: toremo and po'o poó (local names), both from the Carangidae family. Genders Seriola, Pseudocaranx for the central coast of Chile ? Deep fishing by 500 AD ? I do not think so...
Nop. They are ambulacral ossicles from our common starfish (Stichaster striatus).
