I was researching extinct species on Wikipedia, and it struck me how poetic and arcane the Latin names sound. You can imagine Harry Potter reciting them as a spell. I thought that a roll-call of extinct species might form a poem in itself. I wasn’t sure whether to add the common names and dates of extinction, in case it detracted from the flow of the names, but on balance I think it helps to appreciate what has been lost and adds the ‘data’ to the poem. Try saying it out loud three times in a mirror.
