Bones of the biggest ever whale species possibly found?
The uncertainty of science: Paleontologists have discovered a portion of the skeleton of what they claim might be the biggest and heaviest animal ever found, a whale that potentially grew to be as much as twice as big as a blue whale, the largest living species previously known.
A newly described fossilized whale named Perucetus colossus, dating to roughly 38 million years ago, might have been heavier than a blue whale, even if it was not as long. Blue whales, which are endangered, weigh about 100 to 150 tonnes, although some might be as heavy as 200 tonnes. Perucetus colossus was between 85 and 340 tonnes, according to the scientists who found and described the remains: 13 vertebrae, 4 ribs and a bit of pelvis. Their best-guess estimate is that the whale was around 180 tonnes. This mind-boggling mass is the result of its bones, which were big and dense — an evolutionary adaptation that helped it to dive.
The graphic to the right shows the discovered bones in red, with the rest of the theorized skeleton indicated in grey. Only in the article’s next-to-last paragraph does Nature recognize this very very very large uncertainty:
The team chose to create a visual reconstruction of what the whale might have looked like, basing the head on skulls of related basilosaurid species, but they caution that some of the details are speculative. It could have been skinnier. But it also could have been quite a bit longer or fatter, [co-author Eli] Amson says.
In other words, they presently have no idea what the species actually looked like, or how big it actually was. It very well could have been much shorter and thinner than proposed. It appears therefore they chose to highlight the largest possible size to garner the biggest press coverage — which of course they are getting.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to
