The ‘mediotype’: a powerful tool for modern ichnology based on 3D models

چکیده
Vertebrate tracks are subject to a wide range of morphological variation. A single trackmaker may be associated with a range of tracks reflecting individual pedal anatomy and behavioural kinematics mediated through substrate properties which may vary both in space and time. Accordingly, the same trackmaker can leave substantially different morphotypes something which must be considered in creating ichnotaxa. The mediotype concept introduces the idea of using statistically-generated three-dimensional track models (median or mean) as a guide in this process. A representative track is thereby created from a set of individual reference tracks or from multiple examples from one or more trackways. Mediotypes are useful in: understanding the preservation variability of a given track sample; identifying characteristic or unusual track features; or simply as a quantitative comparison tool. They increase the value of ichnotaxonomical interpretations and we argue that they should become part of the standard procedure when instituting new ichnotaxa. As three-dimensional models start to become a standard in publications on vertebrate ichnology, the mediotype concept has the potential to help guiding a revolution in the study of vertebrate ichnology and ichnotaxonomy.

متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کامل3d Ichnology—recovering Digital 3d Models of Dinosaur Footprints
Ichnology deals with the traces of prehistoric organisms and thus with the study of dinosaur footprints and tracks. This paper reports on a reliable and precise methodology developed to integrate high-resolution close range photogrammetry and range sensors for 3D surveys of dinosaur footprints. The 3D footprint and track models recovered here yield a great deal of accurate morphological and mor...

Introduction: Nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. One of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis. Materials and Methods: In this work, a hybrid method based on Geometric Deformable Models...
