This page represents the following TreeOfLife-200M taxonomic path.[1]
The available TreeOfLife-200M images for Brooksella alternata depict fossilized hexactinellid sponge material preserved in museum/institutional collections. Specimens show the characteristic siliceous spicule framework of glass sponges, with visible mineralized skeletal elements that may appear as clustered or reticulated (net-like) structures depending on preservation and imaging angle.
