One day in 2016, paleontologist David DeMar got very lucky. While examining the ground at Hell Creek in the U.S. state of Montana, he found a fossil the size of a golf ball. It was a coprolite — fossilized feces — from a theropod (probably a juvenile Tyrannosaurus rex or a Nanotyrannus). Inside the coprolite was a feather from an aquatic bird (not related to modern birds). With a high degree of confidence, researchers believe the bird spent the final moments of its life in the digestive tract of a teenage T. rex.

Nacho Valle is a restless figure, a distinctive entrepreneur. When he was young he ran a hangout with a friend in the old El Carmen neighborhood that became a benchmark of Valencia’s alternative music and rock and roll scene, Túrmix. After his father’s death he took over the Valle Ortí art gallery. He learned the trade, toured the world visiting fairs, introduced contemporary art into his program and managed to get into the ARCO selection in Madrid. Then the 2012 economic crisis hit, coinciding with his own personal crisis and a certain weariness with a city whose collectors are few in number and mostly prefer to buy abroad. So he left.

On paper, they remained the legitimate operators of the assets, but it soon became clear that, even as those visits took place in plain sight, a plan was being put in motion to take the fields away from them.

Seeing her seated is striking. When she stands, all you can do is look up. Zhang Ziyu is 19 and stands 2.23 meters tall (seven feet and three inches). She is the tallest professional women’s basketball player in history and the main attraction at the World Cup in Berlin, where she is competing with China’s national team, but as she herself points out, she’s still almost a child. “Everyone thinks I’m tough because I’m very tall, but I’m still a young girl, sometimes quite childish,” Zhang says in a FIBA documentary. It shows in her youthful face, in the jokes with her teammates and in the laughter as she runs through the mixed zone. And in her hobby of crocheting handicrafts that she gives to friends, like a stuffed elephant she spent two weeks sewing with yarn.
