Known as Omo Kibish 1 (Omo I), the fossil was dated to 196 ± 5 ka old and is among two other Omo remains (Omo II and Omo III) that were found in Member I. [3] The Omo fossils were more recently (in 2022) re-dated to approximately 233 ± 22 ka old. [4] In the early 2000s a research boom enriched the knowledge base about the Kibish Formation.
This animal was a filter feeder, using its lophophore to extract organic matter from passing seawater. The soft bodied fossils of this genus were important in establishing hyoliths as possible members of the lophophorata alongside brachiopods and bryozoans.

A relict, in geology, is a structure or mineral from a parent rock that did not undergo metamorphic change when the surrounding rock did, or a rock that survived a destructive geologic process. Some geologic processes are destructive or transformative of structures or minerals, and when a process is not complete or does not completely destroy ...

Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.

The fossil has been identified as a new silesaurid, an extinct group of reptiles. Paleontologists debate whether silesaurids were true dinosaurs or possibly a precursor to the creatures that once ...
[1] [2] The sedimentary rocks of formation were deposited in floodplain environments and contain vertebrate fossils, including a diverse assemblage of dinosaur remains. In 1973, the Cloverly Formation Site was designated as a National Natural Landmark by the National Park Service.
