Burma terrane

The terrane was in the upper plate of the subduction zone since early Cretaceous.

[1][2] For a long time it was assumed that it was part of Eurasia since Mesozoic, but more recent geochronology research suggest that it was located near the northwestern Australia margin in the Late Triassic, and paleomagnetic data suggest that the block was at equatorial latitudes on a plate separate from Eurasia from the Cretaceous until the late Eocene.

[2] It is suggested that since the Cretaceous the block was located north of the Andaman Islands in the forearc of the Sunda Trench subduction zone.

[2] Many of the small animals and plants that inhabited the Burma Terrane during the mid-Cretaceous are well-documented due to their exquisite preservation in Burmese amber.

Many of these animals were likely endemic to the archipelago due to its isolation at the time, providing a rare comprehensive example of an insular fauna from the Mesozoic.
