Bifungites

Bifungites is a dumbbell-shaped trace fossil predominately found in Paleozoic rocks from the Cambrian to the Mississippian, believed to be the burrows of extinct animals. A paper published in September 2024 reports the discovery of worms of the Annulitubus genus in Bifungites traces found in rocks from the Devonian Pimenteira Formation of Brazil, the first record of the creatures that created the burrows.^[1]^[2]
