Paleontologists have discovered the oldest belly button known to science on a 125 million-year-old fossil of a dinosaur in the genus Psittacosaurus. Oh, the fossil also had the first dinosaur butthole ever found.

As reported by Live Science, the Psittacosaurus lived during the Cretaceous period, which was between 145 million to 66 million years ago, and the scientists discovered this belly button after they exposed the fossil to a concentrated beam of laser light.

These scientists reported their findings in the journal BMC Biology on June 7 and say they spotted a "thin trace of an umbilical scar" that is a "slight misalignment in the pattern of skin and scaled over the dinosaur's abdomen and is the reptile equivalent of a mammalian belly button."

While fetal mammals get their nutrients from a placenta, birds and reptiles get what they need from a yolk sac that is connected to their abdomens via blood vessels. When these types of creatures hatch, the yolk is absorbed into the body and an abdominal scar is all that remains.

For most birds and reptiles, the scar heals in a few days or weeks, but some reptiles, including alligators, can have the scar "beyond sexual maturity." This fossil has shed new light on dinosaurs and gives an indication that some dinosaurs did have these scars that didn't heal early on.

The fossil, which is known as SMF R 4970, was an early type of ceratopsian called Psittacosaurus mongoliensis that fell into a group of beaked herbivores that include Triceratops. It was discovered roughly 20 years ago, and it was so well preserved because the dinosaur was "fossillized while lying on its back." This also led to scientists discovering the previously mentioned "perfect" and "unique" butthole.

"Using LSF imaging, we identified distinctive scales that surrounded a long umbilical scar in the Psittacosaurus specimen, similar to [scars in] certain living lizards and crocodiles," paleontologist Michael Pittman, an assistant professor in the School of Life Sciences at the Chinese University of Hong Kong, said in the statement. "We call this kind of scar a belly button, and it is smaller in humans. This specimen is the first dinosaur fossil to preserve a belly button, which is due to its exceptional state of preservation."

Aside from its importance to science, this fossil has also been the subject of a "fierce repatriation controversy." The fossil was discovered in an unknown region of China in the 80s or 90s and was "allegedly smuggled out of the country and into underground European markets before being purchased and put on display in 2001 at the Senckenberg Museum in Frankfurt, Germany."

"There is ongoing debate regarding the legal ownership of this specimen and efforts to repatriate it to China have not been successful. Our international team of Australian, Belgian, British, Chinese and American members all hope for and support an amicable solution to this ongoing debate," the researchers wrote in their paper. "We think it is important to note that the specimen was acquired by the Senckenberg Museum to prevent its sale into private hands and to ensure its availability for scientific study."

Thor: Love and Thunder's Chris Hemsworth has revealed that showing his butt in the upcoming MCU film was "10 years in the making" and was basically a dream come true for the actor.

Speaking to Variety at Thor: Love and Thunder's premiere at El Capitan Theatre in Hollywood, Hemsworth shared why this revealing moment is so special to him.

Chris Hemsworth on seeing Thor's butt in #ThorLoveAndThunder: "It was 10 years in the making that scene — kind of a dream of mine. The first time I played Thor I took my shirt off and I thought, 'You know what's gonna sweeten this...'" https://t.co/3aIXbiXW0C pic.twitter.com/kD2wsPN0zL

"It was 10 years in the making that scene — kind of a dream of mine,” Hemsworth said. “The first time I played Thor I took my shirt off and I thought, ‘You know what’s gonna sweeten this… a decade from now it’s all gonna come off.”

Thor: Love and Thunder director Taika Waititi also discussed Hemsworth's big butt moment in the film, saying that Chris worked too hard to not show off his body.

"I feel like we had all talked about it,” Waititi said. “We had talked about, ‘Yeah, we gotta show off this body.’ My whole thing was like, Chris works so hard, you’ve gotta show it off. Don’t cover it up with all these suits and the cape and stuff, it’s not fair!”

In the same chat with Variety, Hemsworth also talked about seeing Natalie Portman as Mighty Thor for the first time, saying that it was "a little stab to the ego, but I quickly got over it and I was in awe of everything she had done."

You can check out a blurred version of Thor's butt at the end of Thor: Love and Thunder's official trailer, and you can thank Russell Crowe's Zeus for making it happen.

Thor: Love and Thunder will be released in theaters on July 8, 2022.

Marvel is headed back to Hall H.

As reported by ScreenRant producer Ash Crossan during a press conference for Thor: Love and Thunder, Marvel boss Kevin Feige confirmed that Marvel Studios will be attending Comic-Con in July when the event returns in-person to San Diego.

Kevin Feige revealed in the press conference for #ThorLoveAndThunder that Marvel Studios will indeed head to Comic-Con next month pic.twitter.com/NiV6u3I1qt

— Ash Crossan (@AshCrossan) June 24, 2022

The return is big news, or rather will bring big news, as Marvel Studios has mostly skipped Comic-Con when the event was held virtually due to the ongoing COVID-19 pandemic. Marvel has also skipped previous years, including in 2018 though Marvel did return a year later in 2019.

With Marvel nearing the end of Phase 4, Feige has gone on record to say that the next big saga for the MCU will be revealed in the "coming months." What better place to reveal it than at Comic-Con's famed Hall H?

A Phase 5 reveal would make sense given Marvel revealed most of Phase 4 the last time it was at Comic-Con in 2019. This included reveals for movies like Black Widow, Shang-Chi, Eternals, Fantastic 4, and Blade, as well as the MCU TV shows like WandaVision and Loki.

There's still plenty left in Phase 4 including the new Black Panther, Ant-Man and the Wasp, Guardians of the Galaxy, Captain Marvel, and Fantastic Four still on the slate as well as shows like She-Hulk, Secret Invasion, Ironheart, and Armored Wars.

But aside from the Multiverse and Kang the Conqueror, the big plotline of Phase 4 has yet to be revealed, though Feige says hints for the next storyline are already available.

What do you want Marvel to announce when it makes its Comic-Con return? Sound off in the comments. And IGN will be at Comic-Con this year so check back for all the latest news and announcements.

FromSoftware is finishing up their next game, which is apparently already near the end of development.

In an interview with Japanese gaming website 4Gamer, FromSoftware and Elden Ring director Hidetaka Miyazaki revealed that the studio's next game is already in the final stages of development.

According to the interview, the publication asked Miyazaki back in 2018 around the launch of Sekiro: Shadows Die Twice how FromSoftware's two unannounced games were shaping up. One unannounced game would go on to become Elden Ring, but this other unannounced game is still in the works, and according to Miyazaki, "development is currently in the final stages."

No word on what this game might be, but one of the high-profile leaks around FromSoftware suggests the studio is working on a new Armored Core game, the company's mech battle simulator.

Miyazaki himself revealed that he is already working on yet another game as director, with plans to work "on a more abstract fantasy than anything we've done in the past."

The interview concludes with Miyazaki sharing that along with these new titles, more updates for Elden Ring are in the works. Considering each of the past Souls games like Dark Souls and Bloodborne received fairly substantial DLC campaigns, we can likely expect the same for Elden Ring.

FromSoftware isn't slowing down after the critical and commercial success of Elden Ring. Already one of the best-reviewed games of 2022, Elden Ring feels like a culmination of FromSoft's legendary SoulsBorne formula. Read IGN's Elden Ring review here.

What are you hoping for, a new Armored Core or a new IP? Let us know in the comments.

Sonic Origins developer Simon Thomley has hit out at Sega following a rocky launch of the remaster collection.

Thomley, who is the founder of Headcannon, the co-development studio for Sonic Origins, has taken to Twitter to vent his frustrations, alleging that Sega introduced “wild bugs” into the game.

“This is frustrating,” he said. “I won't lie and say that there weren't issues in what we gave to Sega, but what is in Origins is also not what we turned in. Integration introduced some wild bugs that conventional logic would have one believe were our responsibility - a lot of them aren't.”

This is frustrating. I won't lie and say that there weren't issues in what we gave to Sega, but what is in Origins is also not what we turned in. Integration introduced some wild bugs that conventional logic would have one believe were our responsibility- a lot of them aren't.

— Stealth (@HCStealth) June 24, 2022

Headcannon previously worked with Sega on the well-received Sonic Mania in 2017. It assisted with Sonic Origins, remastering Sonic 3 & Knuckles for the collection. However, Thomley now alleges that he and his team essentially worked on “a separate project that was then wrangled into something entirely different”.

“We knew going in that there would be a major time crunch and we worked ourselves into the ground to meet it just so this would even be made and released,” said Thomley. “Again, I can take responsibility for my and my team's mistakes, and there were some. Some actual mistakes, some overlooking, some rushjobs, some stuff we noticed but weren't allowed to correct near the end. It's absolutely not perfect and some of it is from us. It's complicated.”

Essentially, Thomley states that he and his team are unhappy with the state of the game.

Since its release, a number of bugs and issues affecting Sonic Origins have been reported by eager fans, and the overall reception has already been less than positive.

“I'm extremely proud of my team for their performance under such pressure, but every one of us is very unhappy about the state of Origins and even the Sonic 3 component,” he said. “We weren't too thrilled about its pre-submission state either but a lot was beyond our control.”

Sonic fans have been disappointed with the number of bugs, such as Tails becoming stuck off-screen in Sonic 2, as well as particle issues and instances of Sonic getting stuck on hills.

"We asked to do major fixes near submission but weren't allowed due to submission and approval rules," said Thomley. "We asked about delays early and repeatedly but were told they weren't possible. We offered to come back for post-release fixes and updates - we do not yet know if this is happening.”

"We want these problems to be addressed,” he added. “We provided a ton of feedback during and after development for both Origins and its Sonic 3 integration. We've done a good chunk of work after our work term was over to fix things, support Sega, and to prepare for future updates."

Elsewhere, Sonic fans aren’t happy after Sonic Origins replaced the original soundtrack for Sonic 3, while Sonic creator Yuji Naka has walked back his suggestion that Michael Jackson was involved with those original tracks.

Elden Ring and Dark Souls developer FromSoftware has today published a new recruitment website that invites candidates to apply for a variety of new positions at the studio. The website claims that the developer is working on “several new projects”, and so it looks like multiple games are in the works at the beloved studio.

複数の新プロジェクトに向けて、幅広い職種のスタッフ募集を開始いたしました。フロム・ソフトウェアで一緒にゲームを作ってくださる皆さんを、お待ちしています。よろしければぜひ、特設サイトをご確認ください。https://t.co/p9FvoxnB9T pic.twitter.com/rvDKkipjQA

— FROMSOFTWARE (@fromsoftware_pr) June 24, 2022

The recruitment page is predominantly written in Japanese, but an English language message says “FromSoftware is looking for development staff to play a central role in several new projects. Let's work together to create rewarding experiences for players around the world to enjoy.”

Following the message is a list of 22 job roles, covering game design, programming, art design, graphic design, animation, art design, visual art, movie design, technical art, sound, production support, development support, and corporate sales. In short; this is a pretty big recruitment drive for FromSoftware.

Among those roles is a research and development position, suggesting that at least one of the projects is still in the very early stages.

FromSoftware is likely riding a high following the colossally successful launch of Elden Ring, which sold over 13 million copies in its first month alone. There’s a chance, then, that one of the several projects in the works at FromSoftware is Elden Ring DLC. While extra content for Elden Ring hasn’t been officially announced, players have discovered areas in the game that they believe will one day become PvP focused DLC.

Of course, among those projects are likely brand new games. An Elden Ring sequel seems somewhat inevitable considering its popularity, but the FromSoft devout will no doubt be holding hope for successors (direct or spiritual) to Bloodborne and Sekiro. However, leaks from earlier this year suggest that the studio may be going back to its mecha period with a new Armored Core game.
