What is palæontology?

Literally, the word translates from Greek παλαιός + ον + λόγος [ old + being + science ] and is the science that unravels the æons-long story of life on the planet Earth, from the earliest monera to the endless forms we have now, including humans, and of the various long-dead offshoots that still inspire today. This community is open to anyone interested in paleontology, fossils, and evolution.

when did our ancestors start hunting?

Our ancestors were tree-dwellerz and mostly survived on fruits and maybe some bugs. They developed tools (ie spears, bows, and arrows) to help us take down larger animals. They probably at some point scavenged and age from carcasses killed by other animals. At what point did we add meat to our routine diet? And how as it affected our diet development?

Largest Animal After the Blue whale.

It seems pretty obvious what is the largest animal of all time, the blue whale. Weighing at maximum recorded at 190 tons and possibly more, it is the largest whale and animal of all time. If so, then what do you think is the second largest animal of all time? Some candidates are included below.

Sauropods: Due to them being very fragmentary, the largest specimens are only estimated to be between 70 to 80 tons. However, they are likely bigger, as the absolute maximum size of these sauropods are not likely represented in the Fossils.

Argentinosaurus- World famous sauropod discovered in Argentina. One of the largest sauropods ever since the 90s, and is the most complete of all megasauropods. Weighs at least 70 tons, and up to 100 tons.

Alamosaurus- Large sauropod living among the Tyrannosaurs, very large sauropod. It was the first sauropod in North America after the sauropod gap. Estimated to be between 30-100 tons.

Puertasaurus- Discovered using only couple bones that are very thick, and is extremely fragmentary. The animal itself was estimated to be between 50 to 100 tons.

Patagotitan- A very close relative of the Argentinosaurus, and discovered with multiple bones, meaning it is relatively complete. The animal while alive is estimated to have been at 50-55 tons, and the species could go up to 100 tons.

Barosaurus- Previously estimated to be much smaller, but was revamped because of a single bone from a single specimen, BYU-9024. The bone may have belonged to a different animal, but assuming it is a barosaurus, it is a very large specimen at at least 60 tons, and up to 100 tons.

Amphicoelias- Described by Edward Cope, the vertebrae that was used to estimate the size of this animal is now lost. The infamous animal was previously assigned as a diplodocid, and now changed to a rebbachisaurid named Maraapunisaurus. The living animal if a diplocid would weight around 120 tons, and if a rebbachisaurid would weigh around 60 tons.

Bruhathkayosaurus- Previously assumed to be a mislabeled tree, new photos have turned up in 2023 that confirms it's existence, but not it's size. If the measurements are correct, the animal would have been between 110 tons to 240 tons, but estimated to be realistically between 110 to 130 tons.

Ichthyosaurs: The Ichthyosaurs actually have a chance to surpass the blue whale's weight, as they are underwater creatures. However, they are even more fragmentary and hard to discover than the sauropods.

Shastasaurus- Largest relatively complete Ichthyosaur, relatively thin for it's size. Conservatively estimated around 60 tons and 21 meters, but the specimen itself has been estimated up to 80 tons.

Lilstock Monster- Fragmentary Ichthyosaur, possibly can grow up to 25 meters, and scaling from a shastasaurus, would weigh around 110 tons.

Aust Collossus- Extremely fragmentary ichthyosaur. Due to it's enormous size, it may have been the largest animal after the blue whale. Scaling from a Shastasaurus, we get a weight at 27 meters and 140 tons.

Sharks: Thanks to the recently sized up megalodon, they belong on this list.

Megalodon- Previously assumed up to 50 tons, the giant shark was recently estimated to be able to grow up to 20 meters or longer and over 100 tons. However, it needs to be kept in mind that this study is controversial, and need to be taken with precaution.

Whales: The mammals who have gone back into the sea, also includes the blue whale. Since they exist, we can relatively accurately measure their weight, and they have may be able to the the second largest title after the blue whale as well.

Bow Whale- A extremely thick, strange whale. It has the largest skull of any animal in history, and has been measured up to 120 tons.

Right Whale- Almost extinct whale, also measured to be able to grow up to 120 tons.

Fin Whale- A long, thin whale that can grow up to 27 meters and weigh up to 120 tons.

Perucetus Colossus- A extremely thick, primitive whale discovered recently. It was estimated to be between 60 to 340 tons, but the higher estimates are very controversial, and realistically estimated to be around 130 tons.

Balaenoptera sibbaldina- Incomplete and enigmatic skeleton discovered in the 19th century. May be a blue whale, but if it was a separate species, scaling from a blue whale, could have gone up to 140 tons.

How would a paleontologist or zoologist know what a hippo looked like?

I know its kind of a joke that this skull belongs to a chubby water pig. But what if hippos were an extinct genus. How would «paleontologist» know what hippos looked like if they only had a skull?

Is there any fossils of stuff like pollen

I know it's probably a really obvious answer but it was a thought I just had. Because, given that flowering plants were very recent (Cretaceous period), how do plants reproduce other wise? Like things like grass, where they wave it around in the air and dispell and catch it that way? or did they rely on insecst like they do now.

Which Mesozoic formation would you feature in a documentary and why?

There are many fossil formations, but the ones that tend to show up in documentaries are mostly the Hell Creek and Morrison formation. If you were make your own dinosaur documentary with six thirty minute episode...

  • A Triassic formation.
  • A Jurassic formation (Other than the Morrison Formation)
  • A Jurassic / Cretaceous oceanic formation
  • A Jurassic / Cretaceous pterosaur formation
  • A Cretaceous formation (your choice)
  • An Extinction event episode

Also, what species would you use from each formation and why?

UPDATE:

Yeah I can feel those who want to see a non dinosaur documentary and I can totally relate. So you can also do Cenozoic and Paleozoic formations (It could help me to because I want know Cenozoic / Paleozoic fossil formations with diverse fauna).

What predator should I use for my short story about the Canadon Asfalto Formation?

For my short story collection in writing, I decided to do one showcasing the tree dwelling Manidens. However, I’m having trouble dev on what dinosaur to feature as a predator for it to run from. So far, my options seem to be Piatnitzkysaurus, Condorraptor and Asfaltovenator.

Southern Nevada sandstone tracks

Took this photo in 2014, a mile from paved road. I know they were made by Therapods maybe 200 million years ago, but would love to hear your educated takes. I’m hunching their existence in this environment is more rare than hitting Megabucks…

My Deinonychus sculpture based on Hector that was sold at Christie for 12 million dollar

Ostrom first published his findings in February 1969, giving all the referred remains the new name of Deinonychus antirrhopus. The specific name "antirrhopus", from Greek ἀντίρροπος, means "counterbalancing" and refers to the likely purpose of a stiffened tail.

Why isn’t Manospondylus valid?

Manospondylus was named in 1892 and Tyrannosaurus in 1905. Shouldn’t the former take priority?
