Data from: Reconstruction of the multielement apparatus of the earliest Triassic conodont, Hindeodus parvus, using synchrotron radiation X-ray micro-tomography
Earliest Triassic natural conodont assemblages preserved as impressions on bedding planes occur in a claystone of the Hashikadani Formation, which is part of the Mino Terrane, a Jurassic accretionary complex in Japan. In this study, the apparatus of Hindeodus parvus is reconstructed using synchrotron radiation micro-tomography (SR–μCT). This species has six kinds of elements disposed in 15 positions forming the conodont apparatus. Carminiscaphate, angulate, and makellate forms are settled in pairs in the P1, P2, and M positions, respectively. The single alate element is correlated with the S0 position. The S array is a cluster of eight ramiforms, subdivided into two inner pairs of digyrate S1–2 and two outer pairs of bipennate S3–4 elements. The reconstruction is similar to a well-known ozarkodinid apparatus model. In addition, the μCT images show that the 'anterior' and 'posterior' processes of the S1–2 elements faced the caudal and rostral ends of the living conodont body, respectively.

X-ray Micro-Tomography (micro-CT)
X-ray micro-tomography (micro-CT) is a non-destructive imaging technique that provides resolution of material microstructures in three dimensions at scales from hundreds of nanometers to centimeters. The technique is used at NASA Ames Research Center to investigate a variety of advanced materials, including lightweight composite heatshields for atmospheric entry, woven materials, parachute textiles and meteoroids. Data are collected using both synchrotron and laboratory-based X-ray sources. Synchrotron micro-CT is performed in collaboration with the beamline 8.3.2 at the Advanced Light Source at Lawrence Berkeley National Laboratory. High-fidelity digital representations of microstructures obtained from micro-CT are used as framework to perform predictive simulations of effective material properties and material response using high performance computing.
