Reconstructing paleo GSSP points

Background

We already have a series of longitudes and latitudes of modern GSSP points. But we need the corresponding ancient coordinates of these points. Fortunately, there is a convenient public API of gplates that we can use to finish this task, i.e., reconstructing paleo GSSP points.

Task

Coding language

Whatever you like, I would prefer using python.

Task description

To reconstruct ancient points, we would need three parameters:

the string of point coordinates which we want to convert,
the paleo time we want to travel back, and
the reconstructing model's name.

The string of point coordinates is provided in the data section. The time span should range from 0 to 1000 Ma ago. Please read the website Reconstruct Points carefully, and choose all the available models which can satisfy the time span requirement. And finish the reconstructing task.

Data Naming requirements

The .geojson files should be named as []ma_spikes.geojson, e.g., 200ma_spikes.geojson.
The .geojson files should be saved in the corresponding directory in the name of the model, e.g., ./spikes_data/MERDITH2021/200ma_spikes.geojson
