An international team has named Musango matusadonaensis, the second Triassic dinosaur from Lake Kariba's rocks known only from Zimbabwe. The researchers suspect the ancient environment set these animals apart from South Africa's dinosaurs, though two species from one area cannot yet test that idea.

Rutgers-led physics models of four mosasaur skeletons find Platecarpus and Tylosaurus lunged faster for their size than Mosasaurus and Plotosaurus. Most of that gap comes from how far each tail could curl, so the split in hunting styles is an inference drawn from anatomy.

Researchers found a 9-million-year-old molar from a water-dependent capybara relative in Chile's Atacama Desert. It adds to evidence that the desert had wet intervals long after its hyperarid core began forming in the Eocene.

Dongoconodon platycauda, a 120-million-year-old swimming mammal from Liaoning, was forming a third generation of teeth, a Nature Communications study reports. The single skeleton cuts against the old assumption that two sets of teeth arose early in mammals, though it cannot show where that pattern began.

Cambridge-led researchers tracing collagen-eating enzymes in 700 bacterial genomes found they reached oxygen-using bacteria around the end of the Ediacaran. That timing matches the fall in soft-bodied fossils, so later gaps may record faster decay, a case built on matching dates.

Researchers describing Megacauda sungei in Nature say the half-metre Jurassic swimmer had a throat built for suckling 165 million years ago. That puts the anatomy for milk-feeding earlier than the last common ancestor of all living mammals.

An Oxford-led team found no animals in 140 samples from Mongolia's Kheseen Biota, a fossil bed formed after animals are known to have existed. That weakens the main argument for an Ediacaran start and leaves room for animals before or during Snowball Earth.

Paul Burke's team used CT scans to name Herugavialis cairensis, a new gavial, from Egyptian fossils filed as Tomistoma since the 1920s. The reread adds a species to the Mediterranean's fossil crocodile record, which the authors tie to past changes in climate and sea level.

Tel Aviv and Nanjing researchers describe Cretodorus noonoo, a 99-million-year-old amber planthopper with mouthparts nearly twice its body length. Scans of the folded mouthparts and the lack of pollen point to a sap feeder that bent them into bark cracks.

Eric del Campo's team names Pampaluctor calibar, a roughly 100-kg saber-toothed marsupial relative from rocks younger than its group was thought to reach. Its presence beside the first North American carnivores weakens the case for a quick takeover, though one skull-less skeleton cannot say how the natives finally vanished.

Oxford-led researchers say the 590-million-year-old Weng'an Biota wrongly caps animal origins, pushing a clock estimate back about 200 million years. The resulting 800-to-700-million-year range depends on which older deposits replace Weng'an as the ceiling.

Bat1K researchers' Nature study of 103 genomes and 44 fossils puts the most likely origin of bats in Europe, 65 to 60 million years ago. The same model places powered flight and echolocation near the root of the tree, before modern bat groups began to split.

Two Field Museum interns named Jeanerpeton, a 309-million-year-old amphibian relative the museum had filed under a known species. A co-author says that species name has become a catchall in the collection, so more fossils filed under it may prove to be separate animals.
