Data from: Early post-metamorphic, Carboniferous blastoid reveals the evolution and development of the digestive system in early echinoderms

Imran A. Rahman, Johnny A. Waters, Colin D. Sumrall & Alberto Astolfo
Inferring the development of the earliest echinoderms is critical to uncovering the evolutionary assembly of the phylum-level body plan but has long proven problematic because early ontogenetic stages are rarely preserved as fossils. Here, we use synchrotron tomography to describe a new early post-metamorphic blastoid echinoderm from the Carboniferous (approx. 323 Ma) of China. The resulting three-dimensional reconstruction reveals a U-shaped tubular structure in the fossil interior, which is interpreted as the digestive tract. Comparisons...
