Dinosaurs

From fins to limbs and water to land

(Harvard University) The study shows how and when the first groups of land explorers became better walkers than swimmers. The analysis spans the fin-to-limb transition and reconstructs the evolution of terrestrial movement in early tetrapods.

T. rex had huge growth spurts, but other dinos grew slow and steady

By cutting into dinosaur bones and analyzing the growth lines, a team of researchers discovered that T. rex and its closest relatives got big thanks to a huge growth spurt in adolescence, while its more distant cousins kept on growing a little bit every year throughout their lives.

Ireland’s only dinosaurs discovered in antrim

(University of Portsmouth) The only dinosaur bones ever found on the island of Ireland have been formally confirmed for the first time by a team of experts from the University of Portsmouth and Queen’s University Belfast, led by Dr Mike Simms, a curator and palaeontologist at National Museums NI.

Large volcanic eruption caused the largest mass extinction

Researchers say they have found more concrete evidence of the volcanic cause of the largest mass extinction of life. Their research looked at two discrete eruption events: one that was previously unknown to researchers, and the other that resulted in large swaths of terrestrial and marine life going extinct.

Ancient life signs under dinosaur-killing Chicxulub crater

Researchers have found evidence for an ancient microbial ecosystem in a hydrothermal system beneath Mexico’s Chicxulub Crater, thought to be the site of the impact that killed the dinosaurs 66 million years ago.

Baby dinosaurs were ‘little adults’

Paleontologists have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed ‘Fabian’, was discovered in 2015 at the Frick fossil site in Switzerland.

Past is key to predicting future climate, scientists say

A group of climate experts make the case for including paleoclimate data in the development of climate models. Such models are used globally to assess the impacts of human-caused greenhouse gas emissions, predict scenarios for future climate and propose strategies for mitigation.
