Spath, 1922

The whorl section in Eupachydiscus is inflated and depressed, almost round in the later growth stages. Ribs are narrow but prominent in the early whorls, becoming thick and strong in the later.

Eupachydiscus is distinct from the mostly later, Campanian - Maastrichtian, compressed and high-whorled Pachydiscus, but somewhat similar to the coeval, inflated and coarse ribbed, Coniacian-Santonian, Pachydiscoides

gollark: The names are defined here:```java @Override public String[] getNames() { return new String[] { "rs", "redstone" }; }```in https://github.com/SquidDev-CC/CC-Tweaked/blob/4c8fd4fc358d034b8346d0a5325039076c1d641b/src/main/java/dan200/computercraft/core/apis/RedstoneAPI.java#L26-L30.
gollark: It's entirely possible they're exactly the same speed and none of this matters.
gollark: Oh, wait, scrolled up and you only want directly connected ones, never mind!
gollark: There's also `peripheral.getNames()` to list connected peripherals and `peripheral.find "modem"` or whatever to find peripherals.
gollark: Or `redstone.getSides()`, which is exactly the same.
