8) Argentinosaurus

Quote:

Argentinosaurus is a genus of titanosaur sauropod dinosaur. An early reconstruction by Gregory S. Paul estimated Argentinosaurus at between 30–35 metres (98–115 ft) in length and with a weight of up to 80–100 tonnes. In 2006 Carpenter used the more complete Saltasaurus as a guide and estimated Argentinosaurus at 30 metres (98 ft) in length. Mazzetta et al. (2004) provide a range of 60–88 tonnes (66–97 short tons), and consider 73 tonnes (80 short tons) to be the most likely, making it the heaviest sauropod known from good material.

I had never heard of this dinosaur, really interesting.

Could you post up the relevant links for this along with any future posts?

Scroll down to see a silhouette of one compared to a man.

Here's another one from paleontology: new DNA evidence suggests that all non-Africans (Europeans, East and South Asians, Hispanics) are part Neanderthal. In other words, after modern man left Africa they interbred to some extent with Neanderthals. And Australian aborigines and New Guineans are also part Denisovan, which is another recently discovered species of prehistoric man:

Analysis of genomes of modern humans show that they mated with at least two groups of ancient humans: Neanderthals (more similar to those found in the Caucasus than those from the Altai region)[7] and Denisovans.[10][11][13] Approximately 4% of the DNA of non-African modern humans is shared with Neanderthals, suggesting interbreeding.[11] Tests comparing the Denisova hominin genome with those of six modern humans – a ǃKung from South Africa, a Nigerian, a Frenchman, a Papua New Guinean, a Bougainville Islander and a Han Chinese – showed that between 4% and 6% of the genome of Melanesians (represented by the Papua New Guinean and Bougainville Islander) derives from a Denisovan population. This DNA was possibly introduced during the early migration to Melanesia. These findings are in concordance with the results of other comparison tests which show a relative increase in allele sharing between the Denisovan and the Aboriginal Australian genome, compared to other Eurasians and African populations, however it has been observed that Papuans, the population of Papua New Guinea, have more allele sharing than Aboriginal Australians.[14]
