Clathrinida

== Overview == The Clathrinida are an order of calcareous sponges found in marine environments. Clathrinida is a well-known non-monophyletic order under the class of calcarea, and was first named in 1958 by Willard D Hartman based on corticalization (body cortex)[5]. The fossil record of calcarea is relatively poor due to the nature of sponge – the fossil remains often don’t have the diagnostic spicules – but it’s certain that they are common in the Paleozoic and Mesozoic but rare in the Cenozoic [7].
