Cretaceous Burmite: “a river runs through it”

[Biotalker]

A calcite river, that is. Here are two burmite pieces that have a vein of calcite running through the arthropod inclusion. In this millipede sample, the calcite seems to have run along part of the dorsal edge of the animal, displacing it downwards. It is best seen in the images from within the millipede exoskeleton. The calcite flow was influenced by the tissue of the previously deposited inclusion. I thought it interesting that the process of cracking and calcite infiltration and solidification does minimal damage to the older tissue.

Here is the second burmite inclusion with a calcite vein, a Ripiphoridae beetle. Here there doesn't seem to be perturbed tissue from the calcite.

 

Does anyone else have amber inclusions with calcite veins to show us?
