Here are the entries for Astrodon and Pleurocoelus from MM #2. Lotsa
misspellings and synonymies:

There are other named species of Pleurocoelus, but they're presently in other
brachiosaurid genera. Longest entry for a brachiosaurid is this one, wherein
there happens to be a Pleurocoelus species:

Seeley in 1893. See also Priodontognathus phillipsii in Nodosauridae.
