Could that be tested deep in the ocean? Might give similar pressures.
I am having trouble finding a good reference, but something I found interesting is just how often the deep sea preserves lineages that died out elsewhere. Besides coelacanths there are sea lilies, slit shells, monoplacophorans, and to some extent nautiluses. All were reasonably widespread in the Palaeozoic, then during the Mesozoic marine revolution – related to the appearance of new predators – disappeared except in this relatively inaccessible refuge.
Yes! I love strandbeesten. One of the projects I’ve been dreaming about for years is to put a strandbeest drive on a bike as a kind of art project. I might have unfettered access to a makerspace in a few months, would be a good project for a laser cutter I think 
What gets me is that, the way evolution works, it’s entirely possible one of those lineages could evolve to once again rule the oceans…
Fascinating if you’re into space and computer history, not so much otherwise:

Nah, but I found this.
And, well, this is interesting.
Different accent, but do you know this one?
This is potentially quite important:

This is like motorcycle trials for airplanes.
Speaking of bike trials:
