IGR.GAR-65: one specimen; postero-lateral view from the left body side; relatively good visibility; body on the left side partially abraded (grinded off during preparation); posterior pereopods (thoracic appendages) and pleopods visible.
IGR.GAR-89: one specimen; antero-ventral view; partially good visibility; antenna, pereopods (thoracic appendages), pleopod setation and uropods visible.
IGR.GAR-90: one specimen; ventral view; inclusion is at the surface of the amber and cracked open showing the interior surface of the cavity and features of the head morphology.
IGR.GAR-92: one specimen; lateral view from the left body side; good visibility restricted to some areas; dorsal surface including striation pattern visible.
IGR.GAR-93: one specimen; visible from two directions, latero-dorsal view from the left body side and latero-ventral view from the right body side; good visibility with exception for the pleopod region; dorsal surface including striation pattern, antennular plate, antenna, oral cone, coxal plates and posterior pereopods (thoracic appendages) visible.
IGR.GAR-94: one specimen; lateral view from the right body side; good visibility, antenna, posterior pereopods (thoracic appendages) and uropods visible.
IGR.GAR-95: two specimens.
