Field Museum Intern Hannah Ranft takes a stab at revising New Zealand lichens

Macrolichens in the family Lobariaceae are among the most conspicuous and charismatic lichens on the planet, due to their often large, colorful thalli and their ecological importance and potential uses. Many species have cyanobacterial photobionts and are capable of fixing atmospheric nitrogen, hence acting as biological fertilizers. Lobariaceae are also good indicators of environmental health and the conservation status of forest ecosystems. Species such as Lobaria pulmonaria have been used in homoeopathic medicine.

Through thick and thin! Stabilizing the Plaster on Minirdis’ Coffin

After cleaning, the first part of Minirdis’ burial equipment that we treated was his coffin.  The coffin was constructed of wood panels joined with wood dowels. A layer of an orange colored plaster like material had been applied over the wood to fill gaps between the wood panels and provide a smooth surface. On top of the plaster layer, the coffin had been painted black with red and yellow decoration.

How to Uncoffin a Mummy

Removing the lid of the coffin was just the start. Now there was the problem of removing the damaged mummy from the lower half of the coffin. With the lid off we found that the right side piece, which had been held in place by the lid, was detached from the bottom of the coffin and could easily be removed. This meant that the mummy could be slid out, instead of trying to pick it up – good news because the assembly was very fragile. Even so, this was no small task, and it took four people to safely move him out of the coffin.
