“The 518-million-year-old fossil Yujingia glutenotunica preserves pinnate filter-feeding appendages and is phylogenetically placed near the last common ancestor of modern ambulacrarians, suggesting that ancestral ambulacrarians were semi-sessile suspension feeders with complex appendages.”

Checks out so far. 2 hold up so far.

0.8800 under ledger-default@0.3.0 at snapshot 27745 for all claims together. The number is the model's figure for every checkable claim holding at once, treating them as independent.

“Yujingia preserved pinnate arms with filter-feeding grooves, and the study inferred that ancestral ambulacrarians evolved from semi-sessile organisms with complex suspension-feeding adaptations.”
