CHW 189 from the private collection of Herman Winkelhorst (Netherlands). The neck of the animal is excellently preserved, but the rest is not. One possible explanation may be that this is the result of uneven colonization of the carcass by microorganisms and algae, which created a protective layer especially around the neck

Doctoral students Daniel Miller, in the water, with Helen Habicht and Benjamin Keisling, handle two recaptured sediment traps from an unusually deep lake in central Maine, where they collected 136 sediment samples spanning the 900-year time span to reconstruct the longest and highest-resolution climate record for the Northeastern United States to date.
