During my field works at Central Hispaniola I have been finding what appear to be manatees/dugongs ribs. As a rookie in the field of paleontology, which I am passionate about, could you help me determine if these dozens of pieces collected, in an elongated form and that are pinching at the end, as ribs of manatee/dugongs correspond or not to these vertebrates? ? They are dense and have small blackish dots like some mollusk fossils that I have also collected. Thanks, infinite thanks for helping me with this dilemma that fascinates me at the same time !!
