I'm freaked out for MIT.

Same freaked out for MIT

pls don't freak it'll be fun

Haha I know it will be fun. But the level of competition is very much intimidating.

Anyhow question! Sorry for the delay (Click to Show Hidden Text)

1. Brachiopoda/Articulata/Mucrospirifer
2. soft muddy sediment in marine waters
3. none? 
4. radula...........................(jk lophophore)

All good except for 3 they did survive the great Permian extinction. And I know 4 is super easy but was struggling of what else to put. Your turn.

hopefully the image shows up...
also, I thought Mucrospirifer only lived in the Devonian...?

1. Class and order
2. what advantages did its "paddles" have in swimming?
3. describe its habitat
4. is it a diapsid, synapsid, or euryapsid?

Wait. How did Mucrospirifer survive the Permian extinction if it is not found after the Devonian?

Reptilia, Plesiosauria, Its paddles were extremely powerful. Some theorize them to be used in a rowing motion or in a flapping motion. Ocean, Euryapsid

I guess they're all correct, but for #2 I was also looking for 4 flippers made it easier to brake and get going

Okay I freaked out and looked through a lot of sources. Basically I have one source that for some reason that change Order Spiriferida (to the name Mucrospirifer) which supposedly is done in some classifications but is uncommon. So this is where the confusion came from. Sorry for the mistake. So basically Mucrospirfer is early to middle Devonian and Spririferida is Ordovician to Jurassic (which is where the problem came from).

Ok cool. But I guess the answer to #2 would depend on the theory you were basing it off of.
