Her companions were all sleeping when the train entered a band of marine fossils. Here exoskeletons, there ancient seaweeds, there a spray of tiny brachiopods.
"The Descent" - Jeff Long
today's invertebrate..............lingula adamsi
he has an objectively correct and wrong answer to every question that has been and will ever be asked
if you pay him a tiny/large amount then maybe he'll give you the answer to an age old question like 'what does it all mean?' or 'why is the sky red now?', but only if you've never flicked or wiggled his stalk (like many have done before)
if you've ever touched his stalk at some point in your life he'll remember it forever and will never talk to you unless you sincerely apologise to him about it

Name: Leptodus Age: 260-299 million years ago, Permian Period Location: Texas, USA, Glass Mountains
Fossils of Leptodus like the one in the photograph are neither fish nor snails, though they’ve been called both. They are shells of brachiopods, and are one of the stranger members of the group.
#953 - Magellania flavescens - Lamp Shell
I literally jumped and yelled when I picked this up on the beach at Leschenault, and realised what it was. Sure, the orange sponge was pretty, but I’d initially thought it was just some bivalve species.
It ain’t. It’s a freakin’ BRACHIOPOD.
I’ve never seen a Brachipod in real life before, except as a fossil - they’re an ancient lineage, unrelated to the molluscs, that have come through mass extinctions since at least the Cambrian, and may have evolved from the Tommotiids of the earliest Cambrian series, 540 million years ago. They have two shells, like bivalves, but the structure and symmetry is completely different, and the internal anatomy even more so. This species, in the Terebratulida has a hole at the rear of the shell, through which the peduncle emerges to attach it to the rocky seafloor. That gives the shell a resemblance to the ancient oil lamps that give them their common name.
Inside the shell brachiopods have a lophophore, a crown of tentacles which filter seawater for food particles. They’re supported on a brachidium - which was still intact in this one!
As you can imagine, I was hugely pleased with this find :)
Name: Marginifera Location: Texas, USA, Glass Mountains Age: 260-299 million years ago, Carboniferous-Permian Periods
The delicate, nearly microscopic detail preserved in this fossil was only achieved through acid. Preparators took advantage of acid's destructive nature and the chemical differences between this fossil and its surrounding rock to keep those details intact.
