Fossil remains associated with amber (NTUG-A-L0103 to L0105). Cretaceous, Hukawng Valley, Myanmar. Scale bars = 1 mm (A–I) and 0.1 mm (J–L). A) Median/proximal columnal (blue arrow) and cirrals (red arrows) of Isocrinus cf. legeri (Repelin). Specimen NTUG-A-L0103. B) Proximal columnal, cirral, and distal brachials (green arrows) of Isocrinus cf. legeri (Repelin). Specimen NTUG-A-L0104. C) Amber surface (NTUG-A-L0105) covering by host sediment containing cirrals (red arrows) of Isocrinus cf. legeri (Repelin) and echinoid spine (yellow arrow). D) 3D renderings of amber surface (NTUG-A-L0104) covering by host sediment containing proximal columnal of Isocrinus cf. legeri (Repelin) associated with large cirral and dozens of small brachials, cirrals, and pinnulars. E) 3D renderings of lateral view of proximal columnal of Isocrinus cf. legeri (Repelin) showing diagnostic tubercles (white arrows). F) 3D renderings of insect (probably an ant) preserved deep inside the amber (NTUG-A-L0104) (A = appendage; H = head). G) 3D renderings of contact between adherent sediment and amber (NTUG-A-L0104) (boundary marked by a dotted red line; S = sediment; A = amber). Blue arrow = proximal columnal of Isocrinus cf. legeri (Repelin), green arrows = small ossicles (possibly brachials, pinnulars, and cirrals). H) Tomographic image of a slice of the amber (NTUG-A-L0104) revealing internal inclusions of small crinoid ossicles (green arrows). I) Section through amber (NTUG-A-L0104) (cut across prior thin-sectioning) showing the internal inclusion of a cirral. J–L) High magnifications of thin section (NTUG-A-L0104) across cirral revealing stereom microstructure under optical (J), polarizing (K), and cathodoluminescence microscopy (L).
