Hamipterus Nest

Hamipterus was a piscivorous pteranodontoid pterosaur that lived in the Early Cretaceous Period in what is now China.

So it seems that I do really love drawing pterosaurs. It’s so much fun. Names of them: Harpactognathus - Cycnorhamphus - Caviramus Hamipterus - Zhenyuanopterus

Pterosaur Eden: The World’s Largest Deposit of Flying Reptile Eggs has Been Found and there’s At Least 16 Embryos in There

Scientists aren’t even done uncovering or studying them but so far they’ve counted 215 Hamipterus tianshanensis eggs and that’s more than all the non-crushed eggs ever found in the whole world of all species of pterosaur. (Illustration by Zhao Chuang.)

The first 3d pterosaur eggs

Fossil finds in China over the past decades have revolutionised out understanding of flying dinosaurs and early birds, but an exceptional discovery of five intact eggs surrounded by dozens of their adult progenitors is providing a wonderful new glimpse into a little understood corner of deep time. The genus was previously unknown, and flitted through the early Cretaceous air during the reign of their dinosaur cousins some 120 million years ago. Up until these, only four confirmed (and badly crushed) pterosaur eggs had ever been found. Hamipterus tianshanensis turned up in the Turpan-Hami basin in Sinkiang, deep in the deserts of northwestern China, abutting the Tien Shan and Pamir ranges. It is one of the world's bleaker places, just south of the dreaded Taklamakan. The surface of the site has only been scraped in the 9 years since excavations started, and many more interesting specimens are expected to appear. The pterosaurs perished in a savage storm way back in deep time, and were rapidly buried in the resulting sediments. The state of preservation of the skeletons proves that they were not carried far after death.

The eggs were soft and bendable with two shells, one hard on the outside, with a membrane within, similar to the eggs of some living snakes. Their parents seem to have buried them on a sandy lake shore, possibly in order to keep them hydrated. The fact that over 40 adults (so far) were buried together in the same storm implies that they hung around in colonies like many modern birds do. The proximity of the gees indicates that they were living near their nesting site, possibly implying parental nurture. Differences in head crests implies that both sexes were present on that long ago stormy day. The adults varied in size from 25cm to 12 metres, pretty hefty in pterosaur terms.

[i-draws-dinosaurs]

prehistoric planet says pterosaur eggs were soft and leathery, have we found any fossils to support that claim?

Yep! Pterosaur egg fossils are very rare, but some beautiful fossils from China show that the eggs had a leathery shell:

This is one of the first pterosaur eggs ever discovered, from Liaoning, and you can see that it's been squashed flat by pressure without breaking! Every other fossil egg with hard shells show cracking patterns from being crushed by the pressure of sediment, but this egg has just been flattened.

On the other hand, this fossil pterosaur egg from Hamipterus seems to have had a thing, but hard, outer shell, since the surface of the fossilised eggshell shows cracking patterns. So they didn't necessarily always have leathery eggs, but we do absolutely have evidence!

Silutitan sinensis Wang et al., 2021 (new genus and species)

(Vertebrae of Silutitan sinensis, from Wang et al., 2021)

Meaning of name: Silutitan = Silk Road titan; sinensis = from China

Age: Early Cretaceous (more precise age uncertain)

Where found: Shengjinkou Formation, Xinjiang, China

How much is known: A series of six neck vertebrae.

Notes: Silutitan was a euhelopodid, a group of particularly long-necked sauropods so far definitively known only from the Cretaceous of Asia. Among the distinctive features of Silutitan were that some of the sheets of bone along the sides of its neck vertebrae had a forked structure (indicated by the blue arrows in the image above). Based on comparison to the more completely known Euhelopus, Silutitan was probably over 20 m long in total body length.

Along with the also newly-named Hamititan, Silutitan is one of the first dinosaurs to be described from the Hami Pterosaur Fauna, a fossil assemblage that includes a preserved nesting ground of the pterosaur Hamipterus.

On a new crested pterodactyloid from the Early Cretaceous of the Iberian Peninsula and the radiation of the clade Anhangueria

The pterosaur record from the Iberian Peninsula is mostly scarce and undefined, but in the last few years some new taxa have been described from different Lower Cretaceous sites of Spain.

Here we describe a new genus and species of toothed pterodactyloid pterosaur from the Barremian of the Iberian Peninsula, Iberodactylus andreui gen. et sp. nov., that shows a close and rather unexpected relationship with Hamipterus tianshanensis from China.

A review of the phylogenetic relationships of the Anhangueria reveals a new family of pterodactyloid pterosaurs, the Hamipteridae fam. nov. being recovered as sister-group of the Anhangueridae. This latter clade can be in turn divided into the new clades Anhanguerinae and Coloborhynchinae. The close relationships of Iberodactylus and Hamipterus shows an interesting palaeobiogeographical correlation between the Chinese and Iberian pterosaur faunas during the Barremian (Lower Cretaceous).

The discovery of Iberodactylus strongly suggests that the clade Anhangueria has clear ancestral ties in eastern Laurasia.

Hi just have a few quick questions 1. Is deltadromus a edaphosaur or a neovenatoroid 2.what is a hamiopterus rookery like and did they take care of there young 3. Would it be correct to call a dinosaur a sileosauroid? Thanks in advance

1. It’s certainly not an edaphosaur, since edaphosaurs are a group of mammal relatives. We’re not sure what it actually is; it may be a noasaurid, a neovenatorid, or a coelurosaur. It’s a weird taxon that jumps around a lot, and we need more fossils before we can say anything more confidently.

2. I’m assuming you mean Hamipterus, since google turned up no results for “hamiopterus”. Hamipterus is known from dozens of individuals buried together in a nesting colony, so we can say a few things: They nested in large colonies, on flat ground that could be easily flooded and buried; the same nesting sites were reused for several years. Their eggs were soft-shelled. The authors suggest that the eggs were buried in the sand upon being laid. The hatchlings were likely not able to fly; this combined with the fact that so many adults and eggs were found together suggests a degree of parental care.

3. No, because “silesauroidea” is not a name that’s ever been used in the technical literature.

A discovery in northwestern China of hundreds of fossilized pterosaur eggs is providing fresh understanding of the flying reptiles that lived alongside the dinosaurs, including evidence that their babies were born flightless and needed parental care.

Scientists said on Thursday they unearthed 215 eggs of the fish-eating Hamipterus tianshanensis – a species whose adults had a crest atop an elongated skull, pointy teeth and a wingspan of more than 11ft (3.5m) – including 16 eggs containing partial embryonic remains.
