“…The preserved anatomical features of the Úrkút dapediid allow its generic assignment and distinction from the eight other dapediid genera (Gibson 2016;Latimer and Giles 2018). Based on the fossil record, among these Hemicalypterus, Sargodon, Dandya and Scopulipiscis seem to went extinct at the end of Triassic, whereas the Úrkút specimen is Toarcian in age.…”

“…1). Scopulipiscis is an extremely large-sized dapediid from the Rhaetian, with a neurocranium that reaches 17 cm in length (Latimer and Giles 2018). This species is substantially different from the Úrkút specimens, which has a full cephalocaudal length of 233 mm, and is Toarcian in age.…”

Dapediidae are a characteristic group of deep-bodied Mesozoic actinopterygian fishes with a moderate diversity at genus-and specieslevel. Here, we add a new occurrence to their patchy fossil record and describe in detail a nearly complete dapediid specimen from the pelagic deposit of the Toarcian Úrkút Manganese Ore Formation in the Transdanubian Range of Hungary. The preserved characters represent nearly all anatomically important body parts and allow assignment to Dapedium and comparison with other dapediid genera. This is the first reported occurrence of the order in Hungary and the Carpathian Basin that extends the known geographical range of the genus to the Mediterranean (western Tethyan) Jurassic. A review of the temporal distribution of published occurrences of dapediids permits speculation that the disappearance of exclusively Late Triassic genera, coincident with the end-Triassic extinction event, was likely related to their specialised feeding strategies and light or incomplete squamation. Multiple environmental crises (warming, acidification and anoxia) severely affected reefal habitats and favoured the survival of the generalist-durophagous Dapedium. The Úrkút specimen adds important data to the Early Jurassic, particularly Toarcian Lagerstätte-dominated fossil record of dapediids. In contrast to the end-Triassic, the Toarcian oceanic anoxic event did not lead to genus extinction among dapediids, possibly prevented by adaptations evolved during the preceding and similarly multi-stressor event. Continuing studies of Mesozoic fish specimens in Hungarian collections may provide new records and insights into other groups as well.Open Access This article is distributed under the terms of the Creative Comm ons Attribution 4.0 International License (http:// creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
