Hesperornithoides

Igama lithetha: “western bird form”1

Yayitya: InyamaIiraptaiJurassic yamva ukuya ku-iCretaceous yokuqala

Hesperornithoides was a small, bird-like dinosaur that lived during the Late Jurassic period. It was a troodontid, a group of smart, fast predators with big brains. This dinosaur was only about as long as a cat, but it was a fierce hunter of insects and small animals.1 4

izinto ezimnandi

Iinyani ezimnandi

Hesperornithoides was nicknamed 'Lori' before it was officially named in 2019.1

Its skeleton was discovered by accident in 2001 while a field crew was digging up a much larger dinosaur called Supersaurus.1

The fossil was found in a muddy sandstone layer that was once a wetland or lake environment.1

Hesperornithoides lived during the Late Jurassic, about 154 to 143 million years ago, in what is now Wyoming.4

This dinosaur had keratin sheaths on its claws, which are rarely preserved in fossils.1

Hesperornithoides was a troodontid, a group of dinosaurs closely related to birds, and its discovery helped show that bird-like dinosaurs lived much earlier than some scientists thought.1

Umfanekiso owenziwe yi-AI: Hesperornithoides — Umfanekiso owenziwe yi-AI obonisa indlela Hesperornithoides esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Hesperornithoides

?How big was Hesperornithoides?

About 89 centimetres (35 inches) long, roughly the size of a turkey or a cat.1 2

?Could Hesperornithoides fly?

No. It had wing feathers, but they were too small for flight.3

?What did Hesperornithoides eat?

It was a carnivore that likely hunted insects and small animals.1

?When was Hesperornithoides discovered?

In 2001, by accident while a field crew was digging up a Supersaurus in Wyoming.1 3

Igama lenzululwazi: Hesperornithoides
Inikwe igama ngu:: Hartman et al. 20194
Iqela: Iirapta
Usapho / iclade: Troodontidae4
Ukuhlelwa: Theropoda > Troodontidae4
Ubudala bamatye: 155 ukuya ku-143 izigidi zeminyaka (Kimmeridgian / Tithonian)4
Izakhiwo zamatye: Morrison4
Amazwe: iUSA4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: The skeleton was found in 2001 by a field crew from the Tate Geological Museum led by William Wahl, while they were excavating a Supersaurus. It was named Hesperornithoides miessleri in 2019 by Scott Hartman and colleagues.1
Kusaxoxwa ngayo: Scientists are not sure if the single known specimen was an adult or a subadult, which affects estimates of its full adult size.1
