A small ditty to the tune of Tom Lehrer's 'The Elements ' (to the tune of something else from a musical, I think)
As performed in Dorset, 2006
There's...
Caulostrepsis, Entobia, and echinoid borings;
Trypanites, Tredolites, Thassinoides burrows.
Planolites, Astericites and a lorenzinia -
Gastrochaenoelites and related genera
There's diplocrateria that dug to stay anoxic
Arenicolites lined with defecations toxic
Skolithos so straight where the planolites are wiggling
Astericites the places where a starfish was a-sitting in
Psilonichus, Macanopsis, Ophiomora, Phylodés,
The rhizocorallium a trace that went all sideways
Spiroraphe Cosmoraphe Helminthoida feeding pits
And the hardest one to say: Taphrelminthropsis
These are all the fossils that we've come to know and love
Examining them closely with the bottoms of our bums!
