The statistics of extinction sized and the taxonomy in trophic model of evolution are investigated. By exploring the parameters of this model, the distribution of extinction sizes N(s) shows typically a characteristic maximum before developing the power-law behavior N(s)≈s-α with α≈2. The derivation of the α = -2 exponent for this model is completed.
