This paper explores the dark sector (dark matter and dark energy) from the perspective of Weyl geometric scalar tensor theory (integrable Weyl geometry). In order to account for the galactic dynamics successfully modelled by MOND ("modified Newtonian dynamics"), the non-minimally coupled scalar field considered here has a Lagrangian with two non-conventional contributions in addition to a standard kinetic term: one is inspired by Bekenstein/Milgrom's RAQUAL ("relativistic a-quadratic Lagrangian") from 1983, the other one by a second order term introduced in cosmological studies by Novello et al. in 1993. {\bf See, however, the error warning below}. We consider the transition to the Einstein gravity on one hand and to scalar field cosmology in the FRW framework on the other. A bouncing cosmological model is tentatively discussed at the end.
