These little trilobites are huge favourites at Timeless Galleries.
The long-extinct trilobite, Eldredgeia, swam the seas of what is now South America and South Africa around 400,000,000 years ago. There is nothing particularly special about Eldredgeia - they aren't especially large, their compound eyes are often well preserved but otherwise unremarkable, their glabella (a bulbous thing in the middle of their head that looks a bit like a nose) is lumpy... however, they do have one redeeming feature: They're often found in nodules.
Opening a trilobite nodule is like cracking open a four-hundred-million year-old egg. Inside is a perfectly formed creature, complete with a mirror-image negative cast.
These trilobites are quite rare and a pleasure to own. Look out for them, or the nodular trilobite, Metacryphaeus, at Timeless Galleries.
Around 10cm in length and mounted on a hand-made cold-cast bronze plinth.
