Tiny bit of wildlife on Hiiumaa

July 1st, 2011

KÄINA, ESTONIA–This is a shout-out to our Wooster Geology colleagues currently working on the barren volcanic island of Iceland. We thought they might want a break from the bleak expanses of black basalt for a little color of wildlife from Estonia. The creature above, of course, is a grasshopper we found in our quarry today.

This colorful moth seems to specialize in the nectar of a common thistle here. It is a Six-Spot Burnet (Zygaena filipendulae).

A native bee on a daisy.

And delicious wild strawberries every day!

Quarry time on Hiiumaa

July 1st, 2011

KÄINA, ESTONIA–Rachel, Nick and I worked today in our lonely quarry on Hiiumaa measuring and describing this section of Lower Silurian (Llandovery, Rhuddanian) rocks and fossils. This is the fieldwork for Rachel’s Senior Independent Study.

One of the dilemmas is the nature of the lower interbedded limestones and shales. In places they show gently sloping beds and curved tops as here. Does this indicate some sort of mud mound or bioherm? Or is it a function of slumping in the quarry itself? (I'm leaning toward the latter.)

The fossils here are excellent, including corals and bryozoans. (Just because I could I expanded the image of the mite!)
