SUPER MEETING: Maybe you thought plans for...

SUPER MEETING: Maybe you thought plans for that super-speed train from Orange County to Las Vegas were dead. Not so--not yet. . . . The bistate commission behind it meets in Anaheim today, with its own survival the top agenda item. The commission, which has seen all proposals fall through so far, has until 1996 to show the California and Nevada legislatures that there’s reason to continue. . . . Says Las Vegas Councilman Arnie Adamsen, a commission member: “We’re feeling some frustrations, but I know of no one yet ready to throw in the towel.”

EARLY ORANGE: If you want to take a look at Orange County a few million seasons ago, a major display of fossil limbs and skulls opens at the Old County Courthouse in Santa Ana on Saturday for a two-month stay. . . . It’s been put together by the county’s Natural History Museum. Everything was unearthed during construction of the San Joaquin Hills and Foothill tollways in South County.

CLOSER LOOK: Almost all of these fossils were dug up by John Minch and Associates, Mission Viejo paleontologists. Included will be Waldo, the 8-million-year-old walrus-like mammal, whose discovery created a stir last year. . . . But Minch says there’s a lot more to get excited about: “Seventy-five percent of this stuff has never been seen by the public before--elephants, camels, bison. We’ve got fossils from some animals whose existence had even been questioned by paleontologists.”

DEJA VU? It’s rare for a sitting judge in Orange County to be challenged for reelection. But Municipal Judge Dan C. Dutcher, who appears to have lost by a mere percentage point to prosecutor Caryl Lee on Tuesday (B1), knows something about such challenges. . . . Dutcher won his Westminster court seat away from incumbent Joanne Harrold 12 years ago. Harrold thumped him easily at the polls, but Dutcher won a court challenge over the legality of her residency, then won the seat she was forced to vacate.
