Data for: Theropod dinosaur diversity of the lower English Wealden: analysis of a tooth-based fauna from the Wadhurst Clay Formation (Lower Cretaceous: Valanginian) via phylogenetic, discriminant and machine learning methods

The Lower Cretaceous Wealden Supergroup of southern England yields a diverse assemblage of theropod dinosaurs, its taxa being represented by fragments in addition to some of the most informative associated skeletons of the European Mesozoic. Spinosaurids, neovenatorid allosauroids, tyrannosauroids, and dromaeosaurids are among the reported Wealden Supergroup clades. However, the majority of relevant specimens are from the Barremian Upper Weald Clay and Wessex formations, and theropod diversity in the older Berriasian—Valanginian Hastings Group has remained poorly known, the fragmentary specimens reported thus far remaining enigmatic both in terms of phylogenetic affinities and sometimes provenance. A better understanding would be welcome given the paucity of Berriasian—Valanginian dinosaurs worldwide. Here, we describe an assemblage of Hastings Group theropod teeth from Valanginian Wadhurst Clay Formation outcrops of the Ashdown Brickworks locality near Bexhill, East Sussex.

## Description of the data and file structure

Morphometric and cladistic data for theropod dental morphotypes I—V were collected via first-hand observation and a DinoLite (AM4113TL) digital microscope. Measurements were taken using a digital caliper and the measuring tools provided in the Dinocapture 2.0 software (v.1.5.48.A).

英国南部下白垩统韦尔登超群（Wealden Supergroup）产出了种类丰富的兽脚类恐龙（theropod dinosaurs）组合群，其类群除保留欧洲中生代部分信息最为详尽的关联骨架标本外，亦有大量化石碎片作为代表。已报道的韦尔登超群支系类群涵盖棘龙科（spinosaurids）、新猎龙类异特龙类（neovenatorid allosauroids）、暴龙类（tyrannosauroids）以及驰龙科（dromaeosaurids）。然而，绝大多数相关标本均采自巴列姆阶（Barremian）上韦尔德黏土组与威塞克斯组，而年代更早的贝里亚阶（Berriasian）-凡蓝今阶（Valanginian）黑斯廷斯群（Hastings Group）的兽脚类多样性却长期鲜为人知，迄今报道的碎片化标本在系统发育亲缘关系乃至部分标本的产出层位上均存在诸多未解之谜。鉴于全球范围内贝里亚阶-凡蓝今阶恐龙化石的稀缺性，对该类群开展更深入的研究具有重要学术价值。本文记述了产自东萨塞克斯郡（East Sussex）贝克斯希尔（Bexhill）附近阿什顿砖厂（Ashdown Brickworks）产地凡蓝今阶瓦德赫斯特黏土组（Wadhurst Clay Formation）露头的黑斯廷斯群兽脚类牙齿组合群。我们对[...]

## 数据与文件结构说明
兽脚类牙齿形态型I-V的形态测量与支序分类（cladistic）数据通过一手观测以及使用DinoLite（AM4113TL）数码显微镜采集获得。测量工作采用数字游标卡尺以及Dinocapture 2.0软件（版本1.5.48.A）自带的测量工具完成。
