From CT scans of 100 lower jaws from African clawed frogs and fire salamanders, we answer the question of whether the amphibian lower jaw evolves as a single unit or evolves with different modules evolving in different ways.
In order to observe the precise morphology of the head bones, we use a micro-computed tomography (micro-CT scanner). This is a 3D imaging technique using x-rays to see inside an object, slice by slice. For our project, we need to…
To collect data on the diversity of shapes and sizes in salamanders, we use micro CT scanning. In this photo gallery we share photos of a recent visit to the CT scanning facility and explain how we create high-resolution meshes from natural history specimens.
Natural history collections are vast repositories of biodiversity data. We share photos of a recent visit we made to a natural history museum to collect linear caliper measurements and other data from the specimens.
