It is generally accepted that conodonts went extinct at the end of Triassic, but younger conodont fossils have been reported, and it becoming clear extinction occurred asynchronously across different regions. Although some reports post-Triassic disproven, Lower Jurassic found in Buda area Hungary Inuyama Japan. Here, we report discovery more Misikella posthernsteini above first occurrence typic...

Conodonts are an extinct group of early vertebrates. Articulated fossils their feeding apparatus (‘natural assemblages’) rare, and preserved soft tissues vanishingly so. Here, a primitive conodont with is redescribed from the Waukesha Lagerstätte Wisconsin, USA. Although derived prioniodontid conodonts well understood, together homologies between taxa, same not true more that have apparatuses c...

The discovery of fossilized conodont soft tissues has led to suggestions that these enigmatic animals were among the earliest vertebrates and that they were macrophagous, using their oropharyngeal skeletal apparatus to capture and process prey. These conclusions have proved controversial. There is now a consensus that conodonts belong within the chordates, but their position within the clade is...

Abstract. Permian–Triassic boundary sections at Baghuk Mountain (Central Iran) are investigated with respect to their lithological succession, biostratigraphy (particularly conodonts, nautiloids and ammonoids) as well chemostratigraphy (carbon isotopes). The rock successions consist of the Late Permian Hambast Formation, youngest Member (new name for “Boundary Clay”) Early Triassic Claraia beds...
