Palaeo After Dark

Dispatched to pursue a giant roaming monolith laying waste wherever it walks join our heroes Bepo the Bard (James), Bix the Druid (Aly), Gregg the Ranger (Curtis) and Kinroth the Wizard (Amanda) as they set out to bring a halt to this lumbering gargantuan structure's meandering path of destruction in a story orchestrated and told by our visiting Dungeon Master (Antony).

The gang goes back to their favorite hypothetical deathtrap amusement park, Penguin Deathland. They discuss two papers that look at the taphonomy of penguin fossil deposits and what they can tell us about ancient environments and the processes that can break down bone. Meanwhile, James loves old movie cliches, Amanda upsets the natural order, and Curt enjoys totally real colors.

 

Up-Goer Five (Amanda):

Today our friends talk about animals with no hair that usually can fly but these can't fly. These are found on an small place surrounded by water that is very cold. These animals lived during the ice age so they are only sort of rock at this time. The first paper looks at numbers of these animals and other stuff all together in one place. The paper shows that there were places where there were baby animals long ago where there aren't any now. It also shows that there were some tiny animals with no rock parts that suck blood that are not on these small places today. But it is possible that some of these tiny animals were brought in later by people.

The second paper looks at how things that are green things and sometimes good to eat not-animals that are living together are hurting the rock parts of these animals with no hair that can usually fly but can't. It turns out that the things that are green things living together with sometimes good to eat not-animals might be very good at hurting the rock parts of these animals, and we can actually see exactly what that looks like and so can tell if we see this in rock parts that would be much much older.
