The phrase is a straightforward noun phrase combining 'order' (a taxonomic grouping) with the taxon name 'Stereospondyli', so its meaning as the biological order called Stereospondyli is directly derivable from the parts. This compositional naming pattern is standard in scientific classification and is cross-linguistically familiar, so a B1 learner who knows both constituents would be able to understand the MWE.

Etymology

Order Stereospondyli comes from Greek roots: stereo meaning 'solid' and spondyl meaning 'vertebra'. It was used for a group of extinct amphibians whose backbone bones were joined into one piece, so the name helps you remember this 'solid vertebrae' feature.
