Please tell me the reference for this "Recent studies show that the Jurassic great-granddaddy of all living mammals probably had a folded brain."

RE: reference?

Sorry for my lack of clarity on this point. The reference for this finding is the one cited in the subsequent sentence, namely my ref.1, Lewitus E, Kelava I, Kalinka AT, Tomancak P, Huttner WB. An adaptive threshold in mammalian neocortical evolution. (2014) PLoS Biol 12:e1002000. Also see ref. 28 therein, which reports a similar finding: O'Leary MA, Bloch JI, Flynn JJ, Gaudin TJ, Giallombardo A, et al. (2013) The placental mammal ancestor and the post-K-Pg radiation of placentals. Science 339: 662–667.
