An employee of the Institute of Earth Sciences of the University of Silesia (Mariusz Salamon) published together with scientists from Poland, Japan, the United States and Taiwan, the article entitled: Paleoenvironmental and biostratigraphic implications of echinoderm ossicles trapped within Burmese amber, in the journal Palaios. The authors reminded that marine organisms are extremely rarely preserved within the ambers. They are rather found on their surfaces or within the sediment surrounding the amber. Currently, the remains of Cretaceous crinoids and echinoids have been found in ambers from Myanmar (formerly Burma). This observation confirms earlier hypotheses saying that Myanmar amber originated in the mid-Cretaceous in the immediate vicinity of the sea.
