Seymchan
This meteorite (pallasite) fell in the Magadan region, near the settlement of Seymchan in Russia, but the date of the fall is unknown. It was discovered in 1967, with the first piece weighing 272 kg discovered in June of that year and the second piece weighing 51 kg in October, just a few months later. Initial examination only discovered the metallic parts of the meteorite and it was only in 2004, during a survey, that 20% of the sample was found to contain olivine crystals and they were able to classify it as a Pallasite.
