1969
The genus Agathis, a group of conifers found in the land areas between New Zealand and Malaysia, has several conspicuous resin-forming systems. Thus, the New Zealand species Agathis australis (Salisbury) produces resins, often in very large amount, in the heartwood, in resin canals in the bark, in resin canals in the leaves, in the leaf surface layers,

X-Ray Diffraction Study of Some Fossil and Modern Resins

Science, 1967
Samples of both fossil and modern resins have been investigated by x-ray diffraction techniques. Most fossil resins (ambers) yield only diffuse x-ray diffraction patterns, though some (settlingite, Highgate copalite, and guayaquillite) have relatively sharp patterns. Many modern resins, including those from species of Pinus

Calyptrate flies in fossil resin from Mexico and Tanzania

Palaeoentomology
Fossil Calyptratae flies are exclusively found in the Cenozoic. Calyptrates arose around the K-T boundary and rapidly diversified in the early Tertiary. Only a few species of fossil Calyptratae are known from fossil resins such as Baltic amber, Dominican amber, and East African copal or Defaunation resin.
