Un estudio dirigido por el doctor Jim Schiffbauer, profesor de la Universidad de Missouri, descubrió en Illinois los restos de una antigua ciudad de hace más de 300 millones de años, los conocidos yacimientos fósiles de Mazon Creek, donde se encontraron 300.000 fósiles.
“Este fue un proyecto divertido que surgió de una manera extraña”, señaló Schiffbauer, sobre la investigación. El geólogo jubilado Gordon Baird fue de gran ayuda en ello, ya que pasó décadas recolectando fósiles de Mazon Creek en Illinois, recibiendo un gran apoyo de los estudiantes durante la pandemia del coronavirus.
“Aquí hay ecosistemas distintos y, de hecho, más de los que Gordon propuso originalmente. Hay agua dulce, hay un estuario y luego hay un ecosistema completamente marino. Así que es realmente genial”, prosiguió explicando.
Encuentran enterrado bajo una ciudad de Estados Unidos un antiguo mundo que está dejando sin habla a los científicos: “Aquí hay ecosistemas distintos”
La zona era antes una gran expansión de agua dulce dominada por peces de río, insectos y plantas, con incluso almejas resistentes y tolerantes, como las medusas. “Hace 300 millones de años, América del Norte estaba un poco torcida y más al sur. El sur de Illinois había estado mirando hacia el oeste”, mantuvo.
Comparado con un posible cambio climático en la época
Aunque el estudio no menciona directamente que esta zona de EEUU se viese golpeada por un cambio climático del momento, Schiffbauer deja caer que pudo producirse por un evento similar a lo que se vive hoy en día.
Comparado con un posible cambio climático en la época
“Es una especie de paralelismo con lo que estamos viendo ahora, en términos del nivel del mar y el calor en el planeta y el aumento del dióxido de carbono en la atmósfera”, explicó.
“El Mazon siempre ha estado en mi lista de deseos. Soy optimista y creo que este será el periódico de referencia para Mazon en el futuro, porque realmente resume y consolida algunas de las interpretaciones previas, y les añade más matices”, sentenció.

US Open: Ageless he isn’t, but Novak Djokovic keeps digging deep and is still alive for major No. 25
NEW YORK — It seems like the old man has spent roughly half of this US Open hunched over at the waist, grabbing at his neck or rubbing his temple. At one point earlier in the tournament, Novak Djokovic even said in an interview with ESPN that he was more concerned about the state of his body than he’d ever been.It’s just what happens when you’re 38 years old, having accumulated so many miles on the legs, playing one of the most demanding sports on earth against opponents in their physical prime.AdvertisementAdvertisementAdvertisementIt hurts.But when Djokovic takes the court, the pain always goes in two directions. And with only two exceptions, it almost defies explanation how often Djokovic still makes his opponents suffer more.[Join or create a Yahoo Fantasy Football league for the 2025 NFL season]It is those two exceptions, however, […]
Lingfield and Bath host competitive Wednesday cards
Motazzen will have to see off Appier and Emaculate Soldier if he is to carry a 6lb penalty to victory in one of Wednesday's feature contests from Lingfield.2.05 Lingfield - Motazzen attempts to defy penaltyMotazzen heads to Lingfield having won his last four starts which include three over hurdles and most recently back on the flat at Southwell and will attempt to go for a fifth win in a row, attempting to defy the 6lb rise from his win in Nottinghamshire last time out. Henrietta Knight's charge picked his way through the field and showed a good turn of foot to win well at Southwell two weeks ago, which earned him a 6lb rise in the weights. At the line he was a shade cosy so you would suggest a bold showing could be expected on his return in this […]
‘Caught cold’ – Athers on England’s ‘curious, calamitous’ South Africa collapse
Michael Atherton urged England to wake up fast after a crushing seven-wicket defeat to South Africa at Headingley, warning their lack of preparation and format adjustment is already jeopardising their hopes of clinching the ODI series.England collapsed from 82-2 to 131 all out in just 24.3 overs, losing their final eight wickets for 49 runs as South Africa cruised to victory to go 1-0 up in the three-match series. Atherton pointed to the potential disruptive impact of the Hundred concluding just two days prior but insisted there was excuse for England's failure to recalibrate to the demands of 50-over cricket."England, without question, have been caught cold," he told Sky Sports. "South Africa look like a side who have been together playing serious international cricket."England's players have been through a month of The Hundred - the eliminator and finals were this […]

‘We will see the best of Lando’ – McLaren boss expects Norris title fightback
McLaren team principal Andrea Stella believes Lando Norris' retirement in Zandvoort will bring out the best of the British driver to ignite a title fightback.Norris trails championship leader Oscar Piastri by 34 points after an oil leak caused by the car's chassis forced him to retire during the latter stages of the Dutch Grand Prix, which was won by his McLaren team-mate. The points gap between the title protagonists is the biggest of this season and it comes with nine rounds remaining, starting with this weekend's Italian Grand Prix at Monza."If anything, we may see even a better version of Lando because now is the time to extract, if there is anything more, even more out of his potential," said Stella."I look forward to seeing Lando in the coming races. I'm sure this is going to be a great spectacle […]
Astros pitcher Framber Valdez denies intentionally hitting his catcher after tense moment in loss to Yankees
Houston pitcher Framber Valdez insists he didn’t intentionally cross up his catcher and hit him with a ball on purpose during the Astros' 7-1 loss to the New York Yankees on Wednesday night.Valdez gave up a grand slam in the fifth inning of the contest at Daikin Park. Before Valdez served up the homer, catcher Cesar Salazar tried to get his pitcher to step off the mound just before he threw the pitch. Valdez ignored that call and threw the pitch anyways, which led to Yankees outfielder Trent Grisham hitting it out of the park. The grand slam gave the Yankees a 6-0 lead at the time.AdvertisementAdvertisementAdvertisementDuring the next at-bat, Valdez drilled Salazar in the chest with a pitch that appeared to get away from both of them. Salazar looked stunned, and eventually took his helmet off and stared at […]
