A surprising factor in the extinction of the dinosaurs may have been how long their eggs took to hatch

Dinosaurs

Approximately 66 million years ago, a massive asteroid or comet smashed into the Earth near what we now think of as the Yucatan peninsula of Mexico. On the other side of the world, in India, at a place called the Deccan Traps, a period of intense volcanic eruption began — one that would last tens of thousands of years.

These catastrophic and powerful events are often considered the primary causes of the mass extinction event at the end of the Cretaceous period that wiped out most of the dinosaurs along with 75% of life on the globe.

But brand-new research reveals another factor that may have played a role in ending the era of the most massive creatures to ever walk the surface of the planet. It seems dinosaur eggs took a particularly long time to hatch. That means that when they had to compete for sparse resources in a post-extinction event world with the more efficient amphibians, reptiles, birds, and mammals that made it through that era into the next one, dinosaurs may have lost out.

Compared to reptiles, birds lay few eggs, and they are particularly large. This could hamper their competitiveness, since it exposes them to destructive risks. But bird eggs hatch about twice as fast as reptiles (their behavior keeps eggs warm and stable), which researchers think helps enough survive to hatch. Dinosaurs still exist in the form of birds — avian dinosaurs — and so researchers thought that the eggs of the non-avian varieties would still hatch at about the same fast rate as bird eggs do. After all, from what we can tell, non-avian dinosaur and bird eggs have similar structures and birds are the only remaining dinosaurs for us to base these hypotheses on.

But the new study, published January 2 in the journal Proceedings of the National Academy of Sciences, reports that dinosaur eggs took far longer to hatch. For one species studied, researchers estimate that a comparable bird egg would take between 40 and 82 days to hatch. The dinosaur egg, it seems, would have incubated between 83 and 171 days before it was ready, more like a reptile.

And that changes a lot of what we know about dinosaurs.

Protoceratops

It’s all about the teeth

The amount of time it takes for young to be born has a significant impact on how a species lives. It can define mating season, migratory behavior, and other characteristics.

Dinosaurs had large eggs and, in general, adults expended more energy than comparably sized reptiles or amphibians, putting a limit on their competitiveness.

By studying the growth of embryonic teeth in other species, researchers have been able to determine how long it took for the infants of those species to develop. So the team behind this study, consisting of researchers from Florida State, the University of Calgary, and the American Museum of Natural History, decided to try to calculate embryonic tooth growth in two dinosaur species, Hypacrosaurus stebingeri (a sort of “duck-billed” dinosaur) and Protoceratops andrewsi (a less-famous relative of the Triceratops).

The researchers saw that a certain measure that can be used to calculate embryonic tooth development in both human and crocodilian species exists in dinosaur species as well. So they evaluated fossil teeth from the above species.

Their calculations showed that the Protoceratops egg would have taken more than twice as long to incubate as a comparable bird egg, and would have been just a bit quicker to develop than a similar reptile. The Hypacrosaurus egg would have incubated even longer, needing more time than a similar reptile.

As the study authors write, this means that many hypotheses of dinosaur behavior may need to be re-evaluated. It was thought that perhaps these species made long migrations back and forth from the Arctic between seasons, but long egg incubation periods may have made this impossible. And while these new findings are just based on evaluations of fossils from two species of dinosaur, the authors say they think these long incubation periods would most likely be found in all toothed dinosaurs — though further research could always change that conclusion.

The other big effect this may have had is on the extinction of these creatures. We already believe dinosaurs expended more energy and needed more resources than reptiles or amphibians. They took a long time to mature, unlike many mammals and birds. When the resources of the world were devastated by a changed climate after the asteroid struck and during the period of volcanic activity, it became hard for any large species to survive. Slow hatching rates would have been just another blow to the non-avian dinosaurs. And that may help further explain why none made it through that time.

14 things that are harder to get into than Stanford

Stanford University

Stanford University’s acceptance rate hit an all-time low for the class of 2020, with 4.69% of applicants accepted into the prestigious California-based school.

That means Stanford is the most selective college in the US, beating out all Ivy League institutions.

But while getting into Stanford might seem like a nearly impossible task, many other achievements in life — like acceptance into some elementary schools — are more difficult than earning a spot within the school’s prestigious walls.

Ben Winsor and Christina Sterbenz also contributed to this story.

A spot at one of New York City’s top elementary schools

The elementary admissions process in New York City is utterly grueling. Among exemplary schools, one stands out as the gold-standard: Hunter College Elementary School.

Each year, Hunter chooses 25 girls and 25 boys from all of Manhattan to be admitted to its incoming kindergarten class.

They’re hand-selected from a pool of about 2,500 applicants, according to the website Inside Schools. That makes the acceptance rate for Hunter 2%. 

 

A job as an NBC page

Landing an internship-like role in the National Broadcasting Company’s page program is competitive to say the least. Famously, the character Kenneth Parcel was a page on 30 Rock.

For example, in 2016 there were 2,600 applicants for 120 positions, for a 4.6% acceptance rate.

The NBC page role is a year-long entry-level role where employees perform PR responsibilities among other tasks depending on their department.

A spot at an innovative startup college


College startup Minerva Schools has received 16,000 applications for 306 available places this year, the Financial Times reported.

Its model vastly differs from four years of school at other prestigious colleges. Students don’t stay in one place during their four-year education.

They spend time in up to seven residence houses in San Francisco, California; Berlin, Germany; Buenos Aires, Argentina; Seoul, South Korea; Bangalore, India; Istanbul, Turkey; and London, England.

At 1.9%, the acceptance rate for the unconventional college is far lower than at Stanford.

“This is the place you will want to be when the SHTF,” or s–t hits the fan, according to a release from Vivos Group. No one calls xPoint home just yet.

The property contains 575 bunkers made of hardened concrete and steel.

Located in South Dakota, the structures were originally built by the Army Corps of Engineers in 1942 as a military fortress that stored explosives and munitions.

The bunkers were built to withstand a 500,000-pound blast from explosives within.

Check out Delta's new Canadian airliner that's trying to challenge Boeing and Airbus (DAL, BBD.B)

Bombardier C Series CS100 Delta

In April, Bombardier Aerospace announced a mega order with Delta Air Lines for 75 of the company’s C Series airliners in a deal worth up to $5.6 billion. Shortly after the deal’s announcement, Bombardier flew one of its C Series demonstrators down to Delta’s Atlanta headquarters for journalists and the airline’s staff to get a closer look.

Although Bombardier has been a global leader in business and regional jets, the C Series is the first product from the Canadian airplane to compete against Boeing and Airbus in the mainline market. The decision to enter the market with the C Series was a major financial gamble for Bombardier, with a program price tag of $5.5 billion. Since its inception more than a decade ago, the aircraft has been beset by a series of development delays and slow sales.

In 2015, the airplane maker was forced to write down $4.4 billion and take a $1 billion bailout from the Quebec government. Even as it struggled to close a sale, Bombardier was credited with building an aircraft that’s one of the most capable on the market today — besting rivals Boeing and Airbus in terms of efficiency and ability.

With the Delta order, Bombardier has not only found a US launch customer for the C Series, but it has the blockbuster deal it needed to validate the attractiveness of aircraft to other prospective buyers. The Bombardier C Series entered service in July with Swiss Global Airlines.

Here’s a closer look at the airliner:

Bombardier offers two version of the C Series: a 130-seat CS300 and a smaller 108-seat CS100.

Delta opted for the smaller CS100, but expect the airline to switch some of its order to the larger jet down the road.

According to Bombardier, the C Series’ greatest selling points are its efficiency and cabin comfort.
