Calceolispongia (literally "shoe sponge") is a diverse genus of cladid crinoids that lived along the shores of eastern Pangaea that correspond to Timor and Western Australia, today.{{Cite journal |last=Teichert |first=Curt |date=1954 |title=A New Permian Crinoid from Western Australia |url=https://www.jstor.org/stable/1300210 |journal=Journal of Paleontology |volume=28 |issue=1 |pages=70–75 |jstor=1300210 |issn=0022-3360}}

When the first fossils were discovered, they were mistakenly thought to be sponges, hence the generic name.{{Cite book |last=Teichert |first=Curt |url=https://books.google.com/books?id=Ho_A8K_wjpAC |title=Permian Crinoid Calceolispongia |date=1949 |series=Memoir |issn=0072-1069 |volume=34 |publisher=Geological Society of America |isbn=978-0-8137-1034-1 |language=en |doi=10.1130/MEM34}} Later, similarly shaped fossils were found, and (correctly) identified as those of a crinoid, and named "Dinocrinus." ("Terrible Lily") It was soon realized that Dinocrinus and Calceolispongia were the same, and Dinocrinus is now regarded as a junior synonym.
