Durante una exploración herpetológica en el Chocó Colombiano y enmarcado dentro del proyecto internacional Ranas Perdidas con el apoyo de USFWS (Wildlife without borders), el equipo de la expedición compuesto por Alonso Quevedo, Felipe Barrera, Uberney Garcia, JuanCarlos Luna, Luis Rubelio Garcia (Fundación ProAves), Robin Moore (Conservación Internacional), Don Church, Wes Sechrest, Nikki Wickman (Global Wildlife Conservation) y Lucy Cooke (periodista), hallaron 3 especies probablemente nuevas para la ciencia, especies muy raras y endémicas del Chocó. |
It seems that Triceratops lived away from rivers, duck-billed dinosaurs dwelled near rivers, and T. rex was equally common everywhere, probably because the beast went wherever there was meat, researchers find. The age of dinosaurs was a time of giants, and near the end of this era, these behemoths often lived surprisingly close to one another in the coastal lowlands of North America. As such, vertebrate paleontologists Tyler Lyson and Nicholas Longrich at Yale University reasoned the titans might have divided the landscape among themselves, so as to not constantly butt heads. |
Como se os dinossauros, ou pelo menos alguns deles, já não fossem grandes o bastante, um novo estudo relata que os esqueletos que vemos em museus deveriam ser até 30 centímetros mais altos do que o são hoje. Os dinossauros, escreveram paleontólogos na revista científica “PLoS One”, tinham grossos pedaços de cartilagem entre suas juntas –e isso aumentava sua altura.
