When the researchers analyzed the amber, though, they discovered a chemical signature known only from the amber of flowering plants.” Rachel Ehrenberg, “Flowerless Plants Also Made Form of Fancy Amber,” Science News, Vol. 176, 24 October 2009, p. 5. u “[The Illinois amber] has a molecular composition that has been seen only from angiosperms, which appeared much later in the Early Cretaceous. ... [Amber resins] are so diverse that those from each plant species have a distinctive Py-GC-MS fingerprint that can be used to identify the plants that produced various ambers around the world.” David Grimaldi, “Pushing Back Amber Production,” Science, Vol. 326, 2 October 2009, p. 51. j.
