==Classification== Leighton & Maples (2002) conducted multiple phylogenetic analyses which are strongly in agreement that the four subfamilies Buxtoniinae, Echinoconchinae, Pustulinae and Juresaniinae form the family Echinoconchidae. The results of their phylogenetic analyses are displayed in the cladogram below:<ref>{{Cite journal |last=Leighton |first=Lindsey R. |last2=Maples |first2=Christopher G. |date=July 2002 |title=Evaluating internal versus external characters: Phylogenetic analyses of the Echinoconchidae, Buxtoniinae, and Juresaniinae (Phylum Brachiopoda) |url=https://www.researchgate.net/publication/250070296 |journal=Journal of Paleontology |language=en |volume=76 |issue=4 |pages=659 |doi=10.1666/0022-3360(2002)076<0659:EIVECP>2.0.CO;2 |issn=0022-3360}}</ref>
