title: Data from: Euconodont hard tissue: preservation patterns of the basal body

description: Conodont elements, consisting of crown and basal tissue are the well-known
 fossilized hard parts of Conodonta (extinct marine chordates), but the
 taphonomic processes leading to decomposition or remineralization of the
 basal tissue are not well understood. Here we focus on the taphonomy of
 basal tissue, reviewing the published record and describing new material
 from Asia and Europe (248 occurrences globally). These include crown and
 basal tissue in conjunction, and isolated basal bodies showing different
 stages of preservation. Some isolated specimens resemble phosphate rings
 similar to those assigned to Phosphannulus universalis. High-resolution
 biostratigraphy indicates that the lamellar type of conodont basal tissue
 is found in all facies and depositional environments. Other basal tissue
 types, described in the literature as tubular, mesodentine, spherulitic or
 lamellar with canalules, are limited to the early Palaeozoic and found
 exclusively in siliciclastic deposits (with the exception of spherulitic
 tissue). Although the stratigraphic record of basal tissue spans the range
 of Euconodonta (Cambrian–Triassic), this study shows that most of the
 isolated plate and ring-like structures are derived from early Palaeozoic
 coniform conodonts. Basal tissue of platform-type elements has a much more
 fragile shape and is therefore rarely preserved as a recognizable isolated
 unit.
