Despite the limited clarity of the images I would be fairly certain that these are fish otoliths. You need to look in the monograph by Dirk Nolf (2013) published by Brussels Museum.
Dear Mohammed! This specimen looks like a small fish otolith, however I can not determine it. If so, You may contact with Werner Schwarzhans (https://www.researchgate.net/profile/Werner_Schwarzhans) or with Bettina Reichenbacher (https://www.researchgate.net/profile/Bettina_Reichenbacher).
... your little fossil also looks like a mineralised seed (semen) of a plant! A foto from the second side of the fossil would be very helpfull for the decision "otolith or seed"!
