Digiphyll - A digital tool for competence building in palaeobotany for teaching and research


Intention

Identifying fossil plants is a key task in palaeobotany. To provide support and easy access to gaining competence in identifying fossil angiosperm leaves, the web platform Digiphyll was developed. Digiphyll is intended to be suitable for teaching as well as for the general public. The ultimate objective is to promote the use of fossil plants in geoscientific research. Digiphyll is designed as an educational portal to provide effective assistance in identifying fossil plant material, accompanied by (1) information on fossil plants as well as (2) offering information about living relatives.


Concept

In fossil leaf material, relevant traits are usually incompletely preserved. The standard approach of a dichotomous key used for extant plants is therefore not well suited for fossil plants. Therefore, an alternative approach was developed which allows to work
(1) with an arbitrary number of recognisable traits and
(2) without a fixed sequence of traits.
To provide a long term continuation of the project Digiphyll was developed exclusively with Libre Open Source Software.


Responsible institutions


Collections contributing fossil images

The following institutions supported the project by contributing specimens from their collections:


Funding

  • Ministry of Science, Research and the Arts, Baden-Württemberg; Funding Initiative: “Kleine Fächer”.

Technical details

  • The web portal was written in the programming language R and is based on the package Shiny as a web application framework.
  • Data of fossil leaves is managed by the database system PostgreSQL (SMNS).
  • Data of extant taxa is managed by the database system 4D (HOH).
