240-million-year-old fossils indicate how dinosaurs grew from hatch...

Paleontologists have found that muscle-scarred fossil leg bones of one of the closest cousins of dinosaurs that lived approximately 240 million years ago can shine new light on a large unknown: How early dinosaurs grew from hatchlings to adults. The findings are surprising: dinosaurs and their close relatives had much more variation in growth patterns then ever expected, and this variation does not appear to be related to differences between males and females.

Evolution has thrown up some weird and wonderful animals over time. Fantastic.

One of the most successful of all the dinos was this humble creature, the Lystrosaurus.

I'll add that to my bucket list. I have a growing collection of fossils, in fact I tiled my kitchen sink wall with real fish/shrimp/bee fossils. Boy does that ever start up some conversations !!!

I really like the shrimp, it's from Lebanon

Thanks! My house is kinda eccentric.

My china cabinet has a bunch of extinct shark's teeth, including a 6" Megeladon

You can see the enamel wear on that big tooth as that giant shark attacked whales, or a wading behemoth, LOL. This other one has a nice tan color from the minerals that fossilized it. I keep a giant Spinosaurus tooth at work, helps me keep perspective when things get crazy.

What a smashing idea Robert. Must be a great talking point.

I went to see the Titanosaur exhibition in the American Museum of Natural History in February. There are plenty of other fossils there, including some that trace the evolution to modern birds.

What a great idea, a sleepover in the Natural History Museum.
