Simulation of Fossil and Taxonomy Data

Simulating taxonomy and fossil data on phylogenetic trees under mechanistic models of speciation, preservation and sampling.

R package for simulating fossil data on phylogenetic trees under mechanistic models of preservation and sampling

The latest version can be installed in R using the package devtools:


Quick start

Simulating data using FossilSim can be as simple as the following code snippets.

# simulate a tree using ape
tips = 8
t = ape::rtree(tips)
# simulate fossils using fossilsim
rate = 2
f = sim.fossils.poisson(rate, t)  
# plot the output
plot(f, t)
# simulate taxonomy using fossilsim
beta = 0.5 # probability of symmetric speciation
lambda.a = 0.1  # rate of anagenesis
s = sim.taxonomy(t, beta, lambda.a)  
# plot the output
plot(s, t, legend.position = "bottomright")
