Morphology
stromatoporoid = stromato + poro + oid
Formed from Greek combining forms plus '-oid' to mean 'relating to or resembling stromatoporoids'; the components are specialist combining forms not recognizable as independent English words, making the derivation non-obvious to average learners.
Etymology
Stromatoporoid comes from Greek parts stroma 'layer', poros 'pore', and -oid 'like', and you can see poros in porous and -oid in asteroid. So when a rock or fossil is called stromatoporoid, it means it has layers and pores like those old reef builders.
