-Andy- Posted February 27, 2019 Share Posted February 27, 2019 Great labelling. These would be helpful for anyone looking to identify similar fossils. Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

Troodon Posted October 17, 2020 Author Share Posted October 17, 2020 Here is a composite right hand I put together with my finds over many years of collecting. Hadrosaur hands are something else and very hard to composite with all different bones.. I will get it mounted at some point when I happy with it. Updated: 10/25/20 with 2 bones from recent trip almost there 42 cm long 9 Link to comment Share on other sites More sharing options...
Dracorex_hogwartsia Posted October 19, 2020 Share Posted October 19, 2020 On 11/19/2015 at 4:18 PM, Troodon said: My next addition to "My Jurassic Park" is with a single species the Hadrosaur: Edmontosaurus annectens. In the late Cretaceous Edmontosaurus was one of the largest and very last Hadrosaurs to exist. It roamed the western North America 66 million years ago and remains are found in its Maastrichtian deposits. Herds of these animals must have been awesome to watch because they were about the size T-rex around 40 ft (12m) long and a great food source for them. All my material was collected from the Hell Creek and Lance Formations. I refer to only one Hadrosaurs species in these deposits based on the 2011 results of a study I noted in the attached post. http://www.thefossilforum.com/index.php?/topic/56733-hadrosaurids-did-you-know/ Although not has sexy as a theropod teeth Hadrosaur teeth functionally are very impressive. In a 2012 study researchers showed that Hadrosaurs evolved extremely sophisticated teeth, more sophisticated than modern mammalian herbivores such as bison, horses and elephants. The study demonstrated that unlike most mammalian molars and pre-molars which are composed of four major tissues the duck-bills evolved a six tissue dental composition which improved the teeth’s ability to grind up food. Hadrosaurs have been identified as “walking pulp mills“ or "Cows of the Cretaceous" and researchers have declared the duck-billed teeth lined jaws as one of the most sophisticated grazing and grinding mechanisms ever to evolve in terrestrial mega herbivores. Their teeth are more complex and better adapted to grinding than most of the large plant-eating mammals found today. A front view of the skull you can see how the tooth batteries are positioned and a cross section of a tooth One of the crown jewel of my collection is one of the finest Edmontosaurs sub-adult skull in captivity at 44" (1.1m) long. Its complete with a partial cervical column and it's preservation is awesome. Still in the field jacket I have yet to decide if I'm going to get it prepped it or just leave it alone A great view of the dentition comes from one of the most interesting specimens I have, an upper and lower jaw section that are fused together. Front Side view I have a few maxilla's in my collection. My favorites are a couple of Juvenile/Baby ones, both are 6" long. An adult specimen can be 17" long. Hadrosaurs have always had a very special place in my heart. My very first dinosaur toy came out of a Nabisco cereal box when I was a kid. It was called Trachodon which is nomen dubium now.

Bobby Rico Posted November 24, 2020 Share Posted November 24, 2020 Fantastic collection and I alway like your image layouts . As you seen I have a few bits of Hadrosaur that I am pretty pleased about. My question was Hadrosaurs the most common dinosaur to be found in Hell Creek? cheers Bobby Link to comment Share on other sites More sharing options...
