Zouologist is a half-brother to good Sydney metro winners Black on Gold and Charlayne, who have also been trained by Chris Waller.
He is the third winner from Fools Gold, a three-quarter sister to Group I winner and $2.3 million earner Driefontein, who is now at stud in Japan.
Fools Gold has been a regular visitor to Widden and has a weanling filly by Zoustar and is in foal to Black on Gold's sire Sebring.
Zouologist is the 50th Australian winner this season for Widden Stud's Zoustar, who is the leading second crop sire by winners, earnings and stakes-winners.
Currently covering his first book of Northern Hemisphere mares at Tweenhills in the UK, the son of Northern Meteor is priced at $154,000 this spring.
