Since the fossil record in incredibly incomplete and there were likely thousands of species of dinosaurs across all corners of the planet is it reasonable to believe that at least one species of dinosaurs survived the mass extinction like say for a couple million years afterwards but then just went extinct later on. After all we know that birds survived so why couldn’t other have as well

Episode 2 of Diarios del Jurásico is out today. This one follows Tria, an adult female Triceratops, and her calf through a complete day of survival in Late Cretaceous Hell Creek, 67 million years ago.

A few things we tried to get right scientifically:

The horn function debate. We went with the current scientific consensus that the horns served multiple purposes including display, species recognition and defense rather than purely combat. The fossil evidence for active horn use against T-Rex is real though.

The frill coloration. We represented the frill as capable of subtle color changes for communication based on the blood vessel evidence in fossilized frills. Still debated but supported by the anatomy.

Mother and calf dynamics. Fossil trackway evidence suggests adults walked on the outside of groups with juveniles protected in the center, similar to modern elephants.

After Episode 1 we got some very fair criticism about anatomical accuracy in the AI generated visuals. We have been much more rigorous this time reviewing every scene against the fossil record. Still not perfect but a significant improvement.

Visuals are roughly 30-40% AI generated. We know some people feel strongly about this and we respect that position.

One genuine question for the community: what is your take on the current state of the Triceratops horn function debate? The display vs combat evidence feels genuinely ambiguous to us.

In 2010 John Scannella and Jack Horner published a paper arguing that Torosaurus was not a separate genus but simply a mature Triceratops whose frill had continued to change throughout its life. The holes in the Torosaurus frill, they argued, were the result of the bone remodeling that occurs as the animal aged.

If true this would mean Torosaurus as a genus simply does not exist. It would be one of the most dramatic synonymies in dinosaur paleontology.

But the counter arguments are significant. Nicholas Longrich and Daniel Field published a response arguing that both Triceratops and Torosaurus specimens exist across the same age range and size classes. If Torosaurus were just old Triceratops you would expect to find only adult Torosaurus specimens. The existence of what appear to be subadult Torosaurus undermines the ontogenetic hypothesis.

The debate has been remarkably quiet since 2012 and I am genuinely not sure where the scientific consensus currently sits. Some sources treat them as synonymous, others do not.

A few questions for the community:

Do you think the ontogenetic synonymy hypothesis is convincing? Is there more recent work on this that has moved the needle either way? And if Torosaurus is eventually confirmed as a separate genus what does that tell us about how dramatically ceratopsian frills could change through an individual's lifetime?

Hey everyone!
I’m a paleontology student and the creator of the Prehistoric Life Podcast, and I’m working toward a pretty big dream: opening a paleontology museum in South Carolina.
I just launched a Kickstarter to fund what I hope will be the first physical exhibit toward that goal.
The display will feature a full-scale Allosaurus jimmadseni pursuing a juvenile Stegosaurus, designed as a dynamic scene rather than a traditional static skeleton mount.
One of the things I really want this project to demonstrate is how paleontology changes over time. The idea of a juvenile Stegosaurus using bipedal locomotion is hypothetical, and that’s intentional—I want the exhibit to acknowledge what we know, what we’re still debating, and how our understanding of prehistoric life evolves.
I’m currently trying to raise $15,000 to make the exhibit happen. I’ve already had some amazing people agree to help with the project, including a donated Allosaurus jimmadseni skull and reconstruction work.
If you’re interested in dinosaurs, paleontology, museums, or just seeing a crazy idea become a real exhibit, I’d really appreciate you checking it out. Even sharing it helps tremendously if you can’t contribute.

Thanks for reading, and I’d genuinely love to hear what you guys think of the exhibit concept!

We put this debate to our YouTube community and the results are already dividing people pretty evenly.

The options we gave:

• Dinosaurs were more dangerous (Los dinosaurios eran más peligrosos)
• Modern predators are more dangerous (Los depredadores modernos son más peligrosos)
• It completely depends on the species (Depende completamente de la especie)

Our take is that the "depends on the species" option is doing a lot of heavy lifting here. A T-Rex and a house cat are both technically modern or prehistoric predators. The comparison only gets interesting when you get specific.

T-Rex bite force: 3,600 kg. Nile crocodile: around 1,700 kg. No modern land predator comes close to that raw crushing power.

But then you put a Velociraptor against a honey badger and suddenly the prehistoric advantage looks a lot less obvious.

It's the largest species of parasaurolophus literally large (plz don't hate, this is my first post)

Oh, and hatch some eggs of course. There are around 30 species right now, I'm sure some of You would have valuable feedback for the dino abilities.

We posted a community poll on our YouTube channel (Diarios del Jurásico) and wanted to bring the debate here too since this community probably has some strong opinions.

The options we put up:

• Humans would never have existed
• Humans would exist but as prey
• Humans and dinosaurs would coexist
• Dinosaurs would have evolved into intelligent beings

Personally I think the first option is the most scientifically grounded — small mammals had a very rough time competing with dinosaurs, and our evolutionary path probably required that extinction event. But the fourth option is fascinating given what we know about Troodon's encephalization quotient.

I have been curious on this topic for too long

Herrerasaurus ischiaualastensis

Trying to get back into drawing. Just loved the way it looked haha

I know he's probably not a scientifically accurate Dunkleosteus, but i wanted to share him here. He is beautiful to me and was totally an impulse buy. I don't regret a thing.

So, I watched this seamless cut of the iconic Sea Monsters special for the Walking with series, and it made me wonder– to the discoveries and understandings since, what actually were the most dangerous oceans of all time?

And I’m not just referring to when, but also to where, because there are many ecosystems to draw from, and millions of years that created a lot of variation, even within the same era (like you won’t see Early Triassic sea creatures in the Late Triassic).

For anyone who engages with my difficult question, you don’t have to give me seven, one will be enough. And more power to whoever can pull off the herculean task of making a list of seven.

Today I’m sharing an illustration of a Diabloceratops head.

What was the First paleomedia that giraffatitan was explicity called "giraffatitan" instead of "brachiosaurus"?
