| 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. | OBSERVATIONAL | Supported | 0.9381 | 1 of 4 | 92 |
| The 518-million-year-old fossil Yujingia glutenotunica is phylogenetically placed within a grade of tentaculate fossils immediately basal to the last common ancestor of modern ambulacrarians. | COMPARATIVE | Supported | 0.9381 | 1 of 4 | 95 |
