One possibility is that DNA of it must've come from drops of blood, partial beetle specimen, or pieces of flesh preserved in amber.
It is unknown as to how these early dinosaurs were recreated as mosquitos haven't evolved in the Triassic period, but amber does exist back then. It was the earliest known dinosaur, the earliest Mesozoic age animal, and one of the geologically oldest known animals that InGen has ever cloned, as well as the only animal from the Triassic period that was ever recreated whereas many of the other animals InGen has recreated was from the Jurassic and Cretaceous period. The primitive saurischian (Lizard-hipped) dinosaur was successfully recreated by International Genetic Technologies (InGen) sometime between the late 1980's to early '90's (before 1993). However, this was not an apex predator as it would've been preyed upon by the 23-foot paracrocodylomorph, Saurosuchus.
At around 16 feet in length and weighing 770 lb., Herrerasaurus, with its mouth full of sharp blade-like teeth with knife-like serrations running up the front and down the back, a lower jaw with a special hinge about halfway along its length to help hold on to struggling prey, and with arms ended in a long five-digit hand with the first three ending in powerful claws used for grasping prey, stalked in the volcanically active floodplains, hunting and preying on synapsids (proto-mammals) such as dicynodonts and cynodonts and other sauropsids such as rhynchosaurs and other early dinosaurs (such as Eoraptor and Panphagia).
In the film, John Alfred Hammond is a flamboyant venture capitalist from Scotland, building his fortune in Petticoat Lane, England.One of the earliest-known and most primitive dinosaurs that ever lived, Herrerasaurus was a bipedal carnivore that lived in what is now the San Juan Province in Northwestern Argentina (Ischigualasto Formation), 231.4 million years ago in the Carnian stage of the Late Triassic period.

2021.01.01: Update for v1.12.6 and Epic Game Store version. He also held parks in Kenya, Costa Rica, and other tropical locations. To create the Indominus rex, the development team acquired the 3D model that was created for 2015's Jurassic World by Industrial Light & Magic, as well as audio files to make the most authentic representation of the hybrid. The only similarities of the film's Hammond to the novel's Hammond are eccentricity and value for money but he is not as much of a dark character. In 1994, InGen sent a recovery team to Isla Nublar, moving the island's Tyrannosaurus to an unknown location prior to its exhibition in Jurassic World many years later.
During the 1997 incident, the InGen team sent to Isla Sorna encountered several Tyrannosaurus. Notes “Add Money” and “Infinite Money” take effects when you gain/spend money.
This mod adds a new dinosaur to the game: Nanuqsaurus, a relatively (keyword "relatively", this is still a big stinkin' animal) small tyrannosaurid that lived in what is now Alaska during the Late Cretaceous.It is unlocked on Isla Sorna with with a little less than half a bar of Science reputation/4 stars in Challenge Mode, and is based off of the Herrerasaurus.
