Birdlike behavior in oviraptoroid dinosaur brooding on nest full of embryos. Found in China. https://www.globaltimes.cn/index.html
-
A long time ago, I came across a picture claiming to be an eggshell from an egg with evidence of hatchling behavior. It looked fairly legitimate - it does really look like the behavior of a small creature pecking out of the shell since the crack is focused on such a small point. My question is, is it possible to tell on smaller or larger eggshell fragments? Take smaller fragments that have cracks running across them like this one: or large entire portions of the egg like this one: What would likely indicate a shell fragment was pulverized by the -

Hey everyone, Have a buddy who went to Fremont Butte in Colorado. He hauled the picture out. Now, I know you will probably need more pics, any chance it is an egg cluster.

Hi, may I have your view on the authenticity and the shell coverage of this pair of eggs?

Think you found an egg? Read this first! Dinosaur Egg Guide- Basic
CBchiefski posted a topic in Fossil ID
The Basic Dinosaur Egg Guide Many people often mistake a concretion for an egg, to help clarify what is a concretion, and what is a real egg, here is a guide. A quick overview with examples: How to spot a concretion: How are they different from eggs? A concretion is a rather common rock made of tightly compressed minerals. Typically, concretions are a smooth sphere or oval with little to no surface texture or just a few bumps. Often nearly a perfect sphere, sometimes more of an oval. In a concretion, there- 17 replies

In some sandstone caves on my property there are layers of conglomerate stones laid into otherwise fine Hawkesbury sandstone. In amongst these there are hollow egg shape structures, some broken off but one in particular in intact but with a hole in it showing that it is hollow. They are all embedded in the ceiling of the cave. the one featured is about 4 inches long. Can some one tell me what they are likely to be?

Can someone please help identify this egg the texture is different from an Oviraptor egg I have? Possibly Macroolithus rugustus?

Hi! This looks good to me, I just want to confirm if this is genuine. Thanks in advance!

Hi All, I'm new to the forum and I have no paleontology experience other than a class from undergrad 20 something years ago. My background is structural geology, hence my post here in hopes that I may confirm my suspicion as to the genesis of the specimens in the attached pictures. First a little background: I was in the field yesterday doing some reconnaissance work in east-central Wyoming. The land owners whose property I was on are multi-generational ranchers and they were extremely welcoming and enthusiastic about the geology of the area, despite having limited knowledge. At the e

Genuine theropod dinosaur eggs?
MohammadAAK posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello all! ive recently purchased this piece (I know I should have consulted beforehand) but I only saw it the last minute before the auction ended. I would still love some insight on it and maybe an actual idea of its locality and species (or genera). The seller claims there is no restoration other than gluing different parts together. He also claims its Enlongatoolithidae either raptor or oviraptor or other therapoda. I would love to have better information on it and even its locality in China, since I assume that’s where it’s from. The fossil is 15 cm long. Unfortunately these a -

Oviposition-Scars On A Calamite Stem From The Westphalian D Of The Piesberg, Germany
paleoflor posted a topic in Member Collections
Dear all, It was difficult, very difficult to wait with posting, since I am very, very excited about this fossil find. However, I also wanted the Dutch magazine version to come out first. Well, it finally did this Tuesday, so here is some info in English, along with a couple of the figures. During a visit to the Piesberg near Osnabrück (Germany) in 2010, I found a stem fragment of Calamites decorated with strange, elongate-oval structures [Fig. 1]. While those features were unusual and quite remarkable, it proved difficult to find information about them and the fossil consequently went into- 25 replies

Hi All, hope everyone had a great Christmas. I hope someone can help, I recently received a quantity of egg shells, originating from China. They are from Oviraptor supposedly. My question is that some have nodes, others have ridges, some have something in between. Is this just something that differs from individual to individual or from species to species? A search on Google images show a selection of both nodes or ridges so I am none the wiser.
