Ganging up on social theropods
Ever since the discovery of four Deinonychus alongside a partial skeleton of Tenontosaurus smack in the middle of the Dinosaur Renaissance, when science was desperate to break the idea of dinosaurs as slow, dumb failures of evolution, every occurence of more than one theropod specimen in the same site has been interpreted as evidence of pack hunting. This is hardly met with criticism since clearly dinosaurs were social animals and stating otherwise would be going back to the times of tail-dragging overburdened lizards. But for what families do we actually have evidence of pack-hunting?
The real answer is none, but gregarious behavior, which is not always equal to pack-hunting, is a different story. So what theropods popularly depicted as pack hunters actually may have been social?

Rose-Colored Mother Earth
South America. 95 million B.C.
Dry season.
Tale told by the cracked, flaky surface of a nearby riverbed. All around, occasional clusters of drying trees are scattered across the dusty terrain. Along the fringes of one such island of tall vegetation, three elephantine Cathartesaura search for whatever food is available, two of them craning their swan-like necks high among the dead branches for dwindling greenery while the third wanders off to examine the ground underfoot. Whistles and cracks from their tails flicking through the air at sound barrier-breaking speeds help the trio keep in contact, along with deep chest rumbles sent and felt through their feet.
Snff snff.
Sweeping its long neck across the barren dirt, the Cathartesaura scours the plains for sustenance. Its nose picks up something moist underneath the dry soil.
Shff shff.
Digging with its snout, the whiptail uproots a cluster of tender roots. It’s not much of a meal considering the large quantities of vegetation neede
