Abstract
Burmese amber originates from the Hukawng Valley in northern Myanmar (Burma). Shi et al. (2012) proposed an age of ca. 99 Ma based on zircon dating, whereas Smith & Ross (2018) proposed an age of 100 Ma based on sediments inside amber produced by bored bivalves. Regarding the plant producing resin Cruickshank & Ko (2003) recorded spores both of Araucariaceae and Taxodiaceae origin. Poinar et al. (2007) proposed an araucariacean origin due to the similitudes with modern kauri pines (Agathis) from New Zealand, while Grimaldi & Ross (2017) suggested the possibility of a Cupressaceae (Metasequoia) origin. Although amber inclusions from Myanmar were first described by Cockerell (1916), great interest (and a huge number of papers) in this biota started only two decades ago.
