It took 66 million years but a Triceratops nicknamed Cera finally made its New York debut—selling at Phillips’ prestigious evening sale last week.
The natural history specimen found a buyer and went for almost $4.4m, with fees, and above its high estimate. However, it did not upstage more conventional lots: a Francis Bacon diptych and Joan Mitchell abstract.
Bacon’s Study for Head of Isabel Rawsthorne and George Dyer (1967) sold for $16m, with fees, pursued by three bidders, while Mitchell’s untitled 1957 painting fetched $14.3m with fees.
Phillips held its evening sale on November 19 and day sales on November 21 during New York’s marquee week. Together they scored a B- on the HENI Auction Index, an improvement on its C- in May.

Bacon’s 1967 diptych, which features his female muse and male partner, returned to the market backed by a strongish guarantee. It sold well above its low estimate, although for $3m less than in 2015, when it fetched $19m, including fees, at Christie’s in London.

Calida Rawles’s Little Swimmer (2016) was another record-breaking work, fetching $193,500. It beat the artist’s previous auction record by $140,200, a 250% rise.
There was also a small decrease in the average hammer to mid-estimate ratio to a level that's 17% below norm.
