required more than 35 years. We believe that the retention of an ectothermal physiology constrained Deinosuchus to the deposition of slow-forming somatic tissues (such as lamellar bone) throughout development, necessitating a greater developmental time to reach dinosaurian proportions.

We found that the coherent backscattering cone of turbid samples containing spherical Mie scatterers with a size parameter larger than about 20 strongly deviates from known analytical curve shapes. We compare experimental data with numerical simulations of Monte Carlo type. Moreover, we present a new wide-angle coherent backscattering setup .

Intensity propagation of waves in dilute 2D and 3D disordered systems is well described by a random walk path-model. In strongly scattering media, however, this model is not quite correct because of interference effects like coherent backscattering. In this letter, coherent backscattering is taken into account by a modified, self-attracting random walk. Straightforward simulations of this model essentially reproduce the results of current theories on "non-classical" transport behavior, i.e. Anderson localization in 1D and 2D for any amount of disorder and a phase transition from weak to strong localization in 3D. However, in the strongly scattering regime corrections are necessary to account for the finite number of light modes due to their non-vanishing lateral extention. Within our model this correction leads to the observation that strong localization does not take place.
